As you know, you can find the number keys in two spots on your keyboard – one is above the letters while the second one is at the number pad. Recently, a number of users reported not being able to type any numbers on their keyboards while some reported that their keyboards only type numbers. This issue could occur on both sets of the number keys or on the one at the number pad. This is a rare situation and seldom happens to users. So if you are one of the few who experience the same problem then you’ve come to the right place as this post will guide you on what you can do to fix the keyboard issue. This issue is most likely due to a switched-off number pad, outdated or corrupted keyboard drivers, turned on mouse keys or it might have something to do with the physical connections. Whatever the cause is, here are some options you have to try to resolve the problem.

Option 1 – Try to enable Numlock

The first thing you can do to fix the issue with the keyboard is to enable the Numlock since one of the most common reasons for this kind of problem is where the keyboard won’t type numbers because the Numlock key is disabled. Thus, you have to enable this key by pressing it once to enable the number pad.

Option 2 – Turn off the Mouse key

• From the Start Menu, go to Control Panel.
• Navigate to Ease of Access Center.
• Then select the option “Make the keyboard easier to use”.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections

You can also try checking if the connection mode you are using for your keyboard is functioning properly. For instance, if you are using a Surface 2-in-device, you can clean the connection pins and see if it resolves the problem.

Option 6 – Run the Hardware and Devices Troubleshooters

Can graphic cards wear out over a longer period of time? Recent studies and experience from crypto miners say no but they can die due to different reasons like improper use, low cleaning habits, factory mistakes, etc. Many gamers and people who use GPU intense applications tend to think that some glitches and hiccups in the software are a sign that graphic card is dying out and that it is time to be replaced. Altho this could be true in many cases these kinds of behavior are mostly due to old drivers and software issues. Older cards can produce these kinds of results due to their old age and new software is often more demanding than these cards can handle. So in order to diagnose and be sure that your GPU is indeed dying out lookout for these signs.

The Main Signs of a Dying GPU:

The Computer Crashes and Won’t Reboot

If your computer shutdown while working in the graphic application or while playing the game and the monitor loses signal there is a high chance the graphic card is soon going to be gone. Some motherboards have hardware detection failure and can signal immediate fail. If when turning your computer ON you are greeted with a blue screen with the message that the signal can not be found or you do not have picture at all it is most likely that GPU has failed.

Graphic Glitches While Playing Games

If you are playing the game and all of sudden you get off-color pixels, screen flickering, strange graphic behaviors, random artifacts, or similar and that keeps repeating in multiple games it is likely that GPU days are coming to an end.

Abnormal Fan Noise or Performance

Fans are an essential part of cooling the GPU and over time if they are intensively used they could wear out and need replacing. If however you have not noticed and have not replaced the fans card can sustain overheating damage. Many cards have cooling fans that are designed to spin at a higher RPM only when the GPU is under load. It prevents bearings in the fans from dying prematurely, so don’t worry if one of your fans is inactive while you are browsing the web. However, when you play games that utilize software that your card isn’t built to support, the bearings in the fans wear out faster. Once the fans stop working under load, the graphics card can quickly die.

How to Diagnose a Dying Graphics Card

Presented next are essential steps in order to recognize a dying graphic card.

Check Motherboard Error Codes

Many motherboards today completely shut down a component that is no longer working. If your graphics card has died completely, this may be one of the easiest ways to tell. If your motherboard doesn’t have display codes, you can try testing the card in a new system.

• Open the computer case: Use your screwdriver to remove screws on the side panel and gently slide it back.
• Locate the error code display on your motherboard: If you have a motherboard with error codes, they should appear near an outer corner.
• Try to reboot your computer: Record each error number you see after you boot your computer.
• Consult the motherboard manufacturer manual for error codes: Open the manual and locate the list for your error codes. If the code matches a graphics processing unit error, your video card could have died.

Check Hardware for Damage or Debris

A graphics card that has damage or debris on the physical parts might quickly overheat and kill the card.

• Remove the screws holding the GPU in place: There are typically one or two screws holding the card to a bracket on the case.
• Unhook the power cords from the GPU and pull the release tab: Remove the power cords from your GPU by pushing in their tabs and gently rocking them out. Once you remove each cord, gently push or pull up on the release tab near the motherboard.
• Inspect the GPU for damage/debris: Check the card for any dirt or debris buildup and clean it out with a Q-tip. You can replace broken fan pieces from the manufacturer.

Test Your GPU Under Load

Download GPU stress-testing and heat-monitoring software.

• With the card installed, run a stress test.
• As you are running the stress test, run heat-monitoring software: With the stress test running, check your heat-monitoring software for GPU overheating. Any reading over 80 degrees Celsius is too hot.
• Check device manager for outdated drivers: If your GPU is clean, but still running too hot, your software drivers are not installed correctly. To check, type in “device manager” at the bottom of your desktop and click on Device Manager. Find your display adapter and right-click on it to see if it’s working. If your drivers are not working correctly, it is indicated here usually. However, the driver may appear to be functioning even if it says otherwise in the properties.

Keep your graphic card drivers updated

When you don’t have the right driver installed, graphics cards can quickly burn up, and their cooling components may fail faster. That’s why you should always keep drivers updated for each new game you install or play. Older games may also release new software patches, so your GPU drivers should be updated accordingly.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 2 – Try running the System File Checker or SFC scan

The SFC scan or System File Checker is a built-in command utility in Windows that helps in restoring corrupted files as well as missing files that cause several issues in the computer like the Windows Update Error 0x800f0900. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Perform a System Restore

You can also try to perform a System Restore as it can also help you fix the Windows Update Error 0x800f0900. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Reset both the SoftwareDistribution and Catroot2 folders

You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder. The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.
