Fix Call of Duty 4 crashes in Windows 10

System Interrupts are operating system processes that function as an alert system for the CPU. So whenever a scenario needs the attention of the CPU, it alerts the CPU about it. In turn, the CPU suspends what it is doing, saves it, and then takes care of that important job and once that job is completed, it resumes back to what it was doing. This indicates that although System Interrupts appears as a process, it’s actually not. As a matter of fact, it is like a manager that reports to the CPU about all interrupts that happen on a hardware level, e.g. hardware interrupts. And if there are lots of interrupts, this means that there might be various errors occurring on a hardware level. As a result, it may take a lot of system resources. And if you consider disabling System Interrupts, stop right there as your computer will almost become useless without it. So if you see System Interrupts consuming high CPU usage in your Windows 10 computer, you can fix it without having to disable it and cause more problems. If System Interrupts takes up more than 5 to 10% of CPU, then you definitely have a problem. This could be happening due to some hardware or driver issue. The first thing you can do is to try rebooting your computer once and see if the issue comes back or not. High CPU usage of System Interrupts is a huge backlog for the CPU and it stays in the loop. If a simple system restart didn’t fix this issue, here are some suggestions you can try.

Option 1 – Try to update the hardware drivers

As stated, the problem might have something to do with hardware drivers so you can try to update these drivers and see if it works.

• Reboot your computer into Safe Mode with networking support.
• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, update all the outdated Hardware drivers on your computer.
• Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
• Now restart your PC and check if the BSOD error is fixed or not.

Note: On the other hand, if a recent update has caused the System Interrupts high CPU usage, then you might want to roll back your hardware drivers to their previous versions. You can check with the Windows Update History to check out any recent updates as well as the previous ones.

Option 2 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

Option 3 – Try to enable or disable Hardware

If you do not want to remove hardware, you can just disable them using the Device Manager. Note that this can also be applied to the internal hardware.

• Tap the Win + X + M keys to open the Device Manager.
• Next, navigate to the device you want to disable.
• Then right-click on it and choose to disable the device.

Note: Make sure that you disable one device at a time and then give it a couple of minutes and check if there are any changes in the CPU usage to pinpoint the hardware. And if there is no change, you need to enable the device you’ve just disabled and then proceed to disable the next hardware device. If there are changes, then it’s probably the culprit. Just keep in mind that you must no disable any device that is needed to keep your system up and running.

Option 4 – Try to update the BIOS/UEFI

Updating the BIOS/UEFI can help you fix the high CPU usage of System Interrupts but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Restart your computer to apply the changes made.

Option 5 – Run the Hardware and Devices Troubleshooter or the Performance Troubleshooter

Hardware and Devices Troubleshooter:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Performance Troubleshooter:

• Tap the Win + R keys to open the Run dialog box.
• Type “exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
• Then click on Next to get started. Wait until the process is completed.

Socket Error 10060 - What is it?

Socket Error 10060 is basically a connection time-out error. This error occurs when the remote FTP server does not respond to CuteFTP. This time-out error occurs after an FTP session is established but even the server doesn’t respond. The error message is displayed in the following format:

‘Connection timed out. A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host failed to respond.’

Solution

Error Causes

Socket Error 10060 may occur due to multiple reasons including:

• Blocked port
• Data connection incorrect settings
• When the web proxy connection setting does not allow enough time to receive a response from the destination website and therefore the connection is timed-out.
• Registry issues
• Viral infection

Further Information and Manual Repair

Here are some of the best and quick DIY methods to resolve Socket Error 10060 on your PC.

Method 1: Troubleshoot the Web Proxy Connection

This method is workable and effective if Socket Error 10060 occurs only when the web proxy service is used. To execute it, here’s what you need to do: install the Winsock Proxy Client on your PC. Disable the web proxy settings under the LAN settings on the Connections tab of the internet options. Once you disable the settings, then try to go to the website that you giving you the error. If the site is accessible, the error is resolved.

Method 2: Increase Web Proxy Time out Settings

If disabling the web proxy settings doesn’t work, then try increasing time-out settings. To do so, you will also have to modify the registry. Remember serious problems may occur if you modify the registry incorrectly.

• Here’s what you need to do, click start, run and then type Regedit in the dialogue box.
• Navigate to the following registry subkey: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW3ProxyParameters.
• On the right side of the Registry Editor, right-click Request TimeoutSecs and then click Modify.
• Click decimal, they type the number of seconds that you want the proxy service to wait until the session times out.
• To confirm changes, click OK.
• Now restart WWW publishing service by going to start, run and type cmd. Click OK to continue.

If you got an Activation Error 0xC004F211 after having installed or upgraded your Windows 10 PC, then this indicates that some hardware in your computer has changed which’s causing the error to pop up. Windows might not be able to determine if the key is used on a new computer or if it’s still the same one if you have just removed or upgraded old hardware. But worry not for this post will guide you in fixing the Windows Activation Error 0xC004F211 on your Windows 10 computer. When you encounter this error, you will see the following error message on your screen:

“Cannot activate Windows 10. Try activating again later. If that doesn’t work, contact support. Error code: 0xC004F211.”

Note that although hardware changes cause this error, the minor ones don’t really cause any issues with activation, however, if you have made any significant hardware change such as replacing your motherboard, it will most likely cause the activation error. In such cases, the Windows Activation system will treat this as new hardware and you will need a new license for that. Even if your Windows 10 computer has a genuine key, it might still fail to get activated which results in the Windows Activation Error 0xC004F211. Thus, before you do other troubleshooting steps, you need to run the Windows 10 Activation Troubleshooter first. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

In addition, there is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

What Is 0x00000050 Stop Error?

While running your Windows 7/Windows Server 2008 R2, your system suddenly stops responding out of complete randomness and you see an error message popping up which says something like this:

0x00000050 (parameter1, parameter2, parameter3, parameter4)

Solution

Error Causes

The stop error 0x00000050 signifies that there’s a PAGE_FAULT_IN_NONPAGED_AREA problem. If you’ve seen this error on different occasions then you will find the parameters in the message to be varying. That is because they are dependent on your PC’s configuration. Not all Stop errors "0x00000050” occur due to a single issue.

However, the most common problem which is encountered which results in the stop error popping up is due to a pool corruption occurring in the Srvnet.sys file.

This issue might be caused because of software incompatibility or a defective physical memory which resulted in requests for data for a hardware driver or service which was not found in the memory.

If you find the error occurring after you’ve installed a new application or a device driver then you should access Safe Mode and uninstall, disable or remove that application or driver.

Further Information and Manual Repair

In order to fix this issue, you should try booting your computer to the “Last Known-Good Configuration” as listed during startup.

For this you have to follow the below-mentioned steps:

1. Start your system.
2. When you see the message which says “For Troubleshooting And Advanced Startup Options For Windows, Press F8” hit F8 and proceed.
3. Use the up and down arrow keys to highlight “Last Known-Good Configuration” and hit enter (This method will only work if your system boot was not successfully carried out ever since you made any specific changes).
4. When you are starting the computer, press F12 and proceed with the PSA/32 Bit Diagnostics.
5. Do the following so that a clean boot can be performed:

• Go to the Start menu when the Windows 7 desktop shows up.
• On the search bar, type “msconfig” and hit search.
• Disable all the applications which are listed on the “Startup” tab.
• Now head over to the “Services” tab and mark the option which reads "Hide all Microsoft Service".
• Select the “Disable All Services” option.
• Apply the changes by clicking on “Apply” then restart your PC. You should now check the performance of your computer. If you don’t see a BSOD then you start re-enabling all the Services and Startup applications one by one until you finally figure out which one is causing the BSOD to appear.

BSOD or Blue Screen of Death errors are one of the most common errors you can encounter on your Windows PC. One of these BSOD errors is the “ACPI_BIOS_ERROR”. If you suddenly get this error, it means that there is some problem in booting the operating system from your hard drive or Windows was not properly installed on your PC. In addition, this error could also mean that there is something wrong with the CMOS battery located in the motherboard. Unlike other BSOD errors, the workaround for this error is a bit different as these workarounds require a bit more expertise in updating the BIOS as well as setting the correct boot configuration. If you know are capable enough in troubleshooting the problem, refer to the instructions laid out below to fix the BSOD “ACPI_BIOS_ERROR”.

Option 1 – Try to remove the SSD and update the BIOS

The first thing you have to do is to check the primary storage devices on your PC. If you have just installed a new hard drive or SSD recently on your computer, then it’s most likely the cause of the BSOD error. Moreover, you should also ensure that your BIOS is up-to-date to the latest available build.

• Remove the SSD/HDD and inject a different HDD that was already preinstalled in your Windows PC.
• After that, update the BIOS to the latest available build. After updating it, insert the old SSD/HDD and then try to boot your PC again. The problem should be fixed now. If not, refer to the next given option.

Option 2 – Try to check the CMOS battery and reset the CMOS module

As mentioned earlier, the CMOS battery might also be the one that’s causing the problem. It is a physical component of the motherboard and is a memory chip that contains all the settings configuration on your computer and is also powered by a battery. So if your battery loses power, the CMOS will be reset and as a result, all the configurations will be gone as well. It is also possible that the CMOS module is not properly working and every time things are saved, they are properly written due to the battery. That’s why you have to consider changing the CMOS battery and see if it fixes the problem. In addition, you also have to make sure that you completely reset the CMOS module and then try booting your PC again.

Option 3 – Try to check the BIOS settings

If the BIOS settings are incorrect, chances are that’s the reason why you’re getting the “ACPI_BIOS_ERROR” BSOD error. Every BIOS has different settings which you can make use of to enhance your computer experience. So make sure that your BIOS is up-to-date and that the settings are in accordance with your requirement. Another thing you can try is to disable the Legacy USB and the Legacy BIOS in the BIOS settings if you are trying to install a 64 bit Windows version. Make sure that you also enable AHCI before plugging in the installation drive on your PC. Moreover, ensure that your PC is using IDE or Integrated Drive Electronics mode instead of SATA or Serial Advanced Technology Attachment. Aside from that, try to check the extracted setup if it is in NTFS format, if it is, you should extract the ISO in FAT32 and use it to install Windows.

Option 4 – Try to reset the ACPI Compliant Control Method

ACPI or Advanced Configuration and Power Interface provide an open standard that operating systems can use to detect hardware, perform power management, as well as monitor the status of your device and provide information for other processes. Chances are, there are some misconfigurations with this module on your PC that lead to believing that there is no battery present. That’s why you need to reset it and see if it fixes the BSOD error or not.

• Boot your PC into Safe Mode.
• Tap the Win + R keys to open the Run dialog box.
• Type in “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After opening the Device Manager, go to the “Batteries” section and click it to expand it and then right-click on the “Microsoft ACPI-Complaint Control Method Battery” option and click on Uninstall.
• After you disable the module, click on any empty space and then click the “Scan for hardware changes” option.
• Then check if you can now boot your PC normally and without the BSOD error.

If you encounter an error saying, “Boot Device Not Found” when you turn on your Windows 10 computer, then you’ve come to the right place as this post will guide you on how you can fix this problem. Apart from the error message, you will also see a message that states, “Please install an operating system on your hard disk, Hard Disk<xxx>”. You will then be asked to tap the F2 key to initiate the System Diagnostics. If you install the Windows operating system, it becomes the boot device, and when your computer boots, the UEFI or the BIOS looks for the operating installed on your drive and continues the process. So when you encounter the “Boot Device Not Found” error, this means that the UEFI or the BIOS wasn’t able to locate the drive where it can boot. There are several suggestions you can check out to resolve this error. You can try checking the connection with your boot drive or change the boot order. You can also fix the Boot Record from Recovery and see if the primary partition is active or not. But before you troubleshoot the problem, make sure that you have a bootable Windows USB drive ready since two of the options provided below will require you to boot into the Advanced Recovery mode. Once you have this covered, proceed to each one of the following options.

Option 1 – Try checking the connection with the boot drive

If you have a custom computer that comes with a cabinet, you might want to open it and remove any connected power supply, and then check the wires. As you know, drives are connected with the motherboard using a cable. So all you have to do is check if both ends are connected properly and make sure that the connection is not loose. You could also try to unplug the cable and plug it back in.

Option 2 – Try changing the boot order

You might also want to try changing the boot order of your computer. Each time a computer boots, the BIOS or the UEFI follows a boot order. It is the one that tells where to first look for the boot drive and if for some reason, a USB is connected to your computer and the first boot device found in the USB, then you have resolved the problem. All you have to do is to remove the USB device and boot or go into the BIOS and change the boot order yourself.

Option 3 – Try to rebuild the BCD files

The next thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
  • bootrec /FixMbr
  • bootrec /FixBoot
  • bootrec /ScanOS
  • bootrec /RebuildBcd

• Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed the “Boot Device Not Found” error.

Option 4 – Try setting the System Partition to Active

Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:

• Boot your computer using the bootable Windows 10 USB drive.
• Next, click Next when you get to the Welcome Screen.
• Then click on Repair your computer located at the bottom left part of the window and select Troubleshoot > Advanced Options > Command Prompt.
• After opening Command Prompt, type the following command and hit Enter to start the Diskpart utility. It is a command line-based utility just like Command Prompt but has a UAC prompt once you provoke it. So if you encounter a UAC prompt, just click on Yes to proceed.

diskpart

• Now type the following command:

list disk

• From there, select your primary disk by typing the following command:

select disk number

• After that, list all the partitions on the selected disk by entering the following command:

list partition

• The command you just entered will list all the partitions created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files.
• Now type the following command to select the partition that is usually around 100 MB in size:

select partition number

• Finally, type the following command to mark the partition active:

active

• Then type the “exit” command to exit the disk part utility.

Once it’s done, the primary drive should now be active and you should now be able to boot into your computer without the “Boot Device Not Found” error.
