If you are one of the few users who is still burning CDs and DVDs, you might have come across an error that says, “Medium Speed Error” or “Power Calibration Error”. There are several factors that could cause this error but it’s most likely that the CD/DVD burner wasn’t able to determine the Optimum Power Calibration rate properly. So what is Optimum Power Calibration rate? It is a test that runs before the burning process to regulate the optimal laser power needed to complete the job. And if this process malfunctions, obviously, you won’t be able to burn the content on your CD or DVD. There are also cases when the Power Calibration error pops up for some small issues that have nothing to do with the regulation of laser power. Here are some quick fixes you can try to resolve the Power Calibration error when burning a CD or DVD.

Option 1 – Make sure you’re using good quality CD or DVD

A lot of burning issues stem down to the purchase of low CDs or DVDs to make sure that what you are using has good quality for it is not always a good idea to purchase cheap products as cheap products could also mean cheap quality.

Option 2 – Try burning at lower speeds

If you’re certain the problem is not with the CD or DVD you are using then you can try burning again, this time at lower speeds. There are instances when doing things quickly can end in a disaster such as the “Medium Speed Error” or “Power Calibration Error” you’re getting.  To fix the problem, you have to burn at a slower speed and just take the time to wait until the burning process is done.

Option 3 – Try updating your burning software

It’s always a good idea to check if the burning software you’re using requires an update especially if it’s throwing up “Medium Speed Error” or “Power Calibration Error”. Thus, you need to update your burning software right away and then try to burn your CD or DVD once the update has been completed.

Option 4 – Try cleaning the disk drive

You might want to consider cleaning the disk drive using several tools in the market that is designed to clean the disk drive. These tools work on removing dust particles from the lens which helps a lot in the burning quality. Aside from that, it also helps in reducing errors like “Medium Speed Error” or “Power Calibration Error”. So give this option a try as it might time for a disk drive cleanup.

Option 5 – Try to disable the IMAPI

If none of the options given above worked, you might want to disable the IMAPI or Image Mastering Applications Programming Interface. How? Refer to the steps below.

• Open Control Panel by simply clicking the Start button and then typing “control panel” in the field.
• Control Panel should pop up in the search results. Once you found it, click it to open it.
• Next, select System Security > Administrative Tools and then click Services.
• After that, you’ll have to search for the “IMAPI CD-Burning COM Service” option.
• Then right-click on it and select Properties.
• From there, switch the Startup Type from “Enabled” to “Disabled”.
• Now click on Apply and then restart your PC.

In today's digital life, when we access the internet daily, browsers are essential almost as our operating system, after all, we do access all of the internet data via them, and having a good, reliable, and personal browser tailored for our needs can make all the difference in the world. In today's article, we will introduce you to the five greatest browsers of today, we will point their advantages and disadvantages and why should you pick one or another. As with each piece of software, there is not an ultimate browser, better than anything else and we will not favor anyone on this list, the decision which you should use is solely up to you, we are here to provide you with an objective opinion on each one. All of this being said, let's begin with the countdown in no particular order.

1. Mozilla firefox.

   If you consider yourself a power user or you value your privacy then firefox is the browser for you. It is open source and is packed with great features like reporting when your email has been used for a known data breach, it stops annoying pop-up notifications, stops browser fingerprinting, and many more. Firefox is also a cross-platform browser making it a great choice if you want to transfer and use your data across multiple devices with one account. The downside of firefox however is its speed, this browser is the slowest on this list, I guess features and advantages took their tool in the speed department, but if that is not a concern for you and you feel like the positives outweigh some slower speed, grab it here.

2. Google Chrome

   Chrome browser has been a game-changer when it was released and even today some of its features are still great and needed. It is packed with some great features like tab freezing, for example, it is cross-platform meaning that also as firefox you can change data between browsers on different devices. it is a very expandable browser with tons of extensions and its speed performance is very very good. The downside of Chrome are two things sadly, one of them is its hunger for RAM, the browser takes a big chunk of RAM once it is active and on some older computer with limited RAM it performs slowly, another is telemetry which its sending, in other words, other browsers don’t come with the lingering fear that Google’s just a little bit too involved in all of our lives. But if downsides do not trouble you and you have a decent amount of RAM in your system chrome might be the best solution for you, grab it here and check it out.

3. Microsoft Edge

   Or should I say Microsoft edge 2.0 since this new Edge is completely recoded and rethought, a completely new browser based on chromium. The first version of the edge was an inhouse attempt from Microsoft and it was a disaster, I guess the lesson was learned, and this new edge we have today is a great Browser, it is lightning fast and packed with some great features with one among them standing out I just love, that is the ability to save web pages as applications and truth to be told you have to try this in order to see al great advantages it offers. A very interesting feature is that edge itself wins the speed race from all of the 5 contestants here which is a great surprise. Of course, the downside of annoying Microsoft pushing it to be your default is, well it's Microsoft, as chrome is tied to Google so is edge tied to Microsoft, and the same dreaded feeling that big MS is watching you. If however, you do not concern yourself with these kinds of things, since it is already part of Windows 10, give it a spin and try it, I am sure you will at least love its blazing speed.

4. Vivaldi

   A new kid on the block, relatively unknown Browser Vivaldi offers some great customizable features no other one on this list offers, a very unique and down to each detail customization option, you can literally tweak each and every aspect of this browser making it best customizable and personal browser ever. How it is also based o chromium, every chrome extension works in it naturally. It is very good in speed and constantly updated and developed. The downside, well if you are anything like me, you could spend ages trying to customize it, ages, it has tons of features, and making it really feel and tick as you want can consume a really lot of time. If this thing does not bother you at all, grab Vivaldi here.

5. Opera

   Last but not least, we have another relic of the old browser age, the Opera browser. Packed with great security and great in-house features like a built-in VPN, built-in ad blocker, built-in crypto wallet, etc this browser seems like a swiss army knife. Opera is full of features and it shows once you start using it. The downside of opera is that its look and feel are specifically tailored to a certain type of user and not everyone will find that appealing or attractive, add some great but hidden and hard to come by features and it may go unnoticed. However, I think you should really give it a go since it definitely deserves more attention than it gets. Grab it here and check it out.

That's it, 5 great browsers to look up, I hope that you have enjoyed the read and I hope to see you again here for more articles. If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.

Cache files are temporary files that have been created by various applications and services when used.  As temporary files, they are safe to be removed and deleted from the system since the application or service will create new ones when needed but sadly will not remove old ones, this task is left to OS itself. Automatic Windows cleanups can mostly take care of these things but for top-notch performance clearing cache manually is a far better option. We will here explore various cache temporary files, where they are, and how to clean them. Sit back and let’s do some cleaning!

Clear cache using Disk Cleanup

1. Open Start menu and search Disk Cleanup
2. Click on it in search results
3. Click on the drives drop-down menu and select the drive where is Windows 11 installed
4. In the Files to Delete section enable all boxes and click on OK
5. Click on delete Files to confirm

Clear Microsoft store cache

1. Press ⊞ WINDOWS + R to open the run dialog
2. Type in WSReset.exe and press ENTER
3. Black blank windows will appear, wait for the window to close itself and you are done

Clearing location cache

1. Press ⊞ WINDOWS + I to open location history
2. Select Privacy & Security
3. In the App Permissions section click on Location
4. On-Location page click on Clear

Clear and flush DNS

1. Press Start and search for Windows Terminal
2. Click on Terminal in search results
3. Type in: ipconfig /flushdns and press ENTER

And that is that!

It has been some time since the release of Diablo 2 resurrected and overall reception was pretty good. People are enjoying the old classic game in hi-def. resolution and with new and improved visuals. Sadly some server issues are present still until this day and somewhat spoil the experience for players. The greatest lag and server crashes are pinpointed to game-creating events. When a player creates a new online game, the server needs to pull a lot of details from the database and make a game, due to some legacy code present this process takes some time and it is demanding a bit on the server-side, and although code was optimized to cater to more modern approach some legacy code still remains. Another thing that was spotted to affect performance itself is player behavior, to be more specific, modern gamer behavior. Where players find good builds and runs on the internet and then go to farm-specific areas or bosses for loot or experience points, which in return boils down to making plenty and short runs that are made by creating games and after run eliminating them. Now pair that with the previous statement about legacy server and database code and you can add 1 and 1 and see how this might be an issue. A lot of short games over legacy code are placing games in a state it was not designed for back in 2001 and therefore we have issues. Sadly solutions without completely rewriting the whole code are not very promising and they include rate limiting, which will prevent players to create many games in succession in a short period of time and maybe even login queues to drop a load on servers. Blizzard reached to people in the whole company, even old diablo 2 developers to ask for advice and they say that they are working on solutions so they could lift limitations and have everything running fine.

For a while now, Microsoft has been working hard to add various built-in troubleshooters in Windows 10. In fact, there is a troubleshooter for almost every standard or common error in Windows 10. And now with the newly released Windows 10 v1903, Microsoft has added the Recommended Troubleshooting which allows Windows 10 to automatically fix a lot of critical issues on your computer, and in this post, you will be guided on how you can turn on or off the Recommended Troubleshooting in Windows 10. The Microsoft Diagnostic & Feedback data only provides two settings – Basic and Full. So if you want to turn off the Recommended Troubleshooting for some reason, the only way to do so is to stop it from collecting complete data from your PC. And to turn it on or off, you can choose to switch between them. To do that, navigate to Settings > Privacy > Diagnostics & feedback and from there, select Basic under the Diagnostic Data section. After that, go back to Settings and go to Update & security > Troubleshoot. Once you’re there, you should see a warning message saying, “Share Full Diagnostic data to get additional troubleshooting recommendations”. Based on the message, Microsoft will only offer the recommended troubleshooting based on the Full Diagnostic data which it collects from your computer. On the other hand, if you know how to navigate and use the Windows Registry, then you can enable or disable the Recommended Troubleshooting via Registry Editor but before you proceed, make sure that you create a System Restore point. Once that’s covered, follow these steps:

• Tap the Win + R keys to open the Run dialog box and type “regedit” in the field and tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoft
• From there, look for the key named “WindowsMigration”. If you can’t find it, just right-click on the left pane and create a new key and then name it “WindowsMigration”.
• After that, create a DWORD “UserPreference” and double click on it to set its value to “0” if you want to turn it off or “1” if you want to turn it on.
• Exit the Registry Editor and restart your computer to apply the changes made.

Note: The Recommended Troubleshooting functionality can look into the error logs sent back to the Microsoft team and use an algorithm to set up a solution for you and they’re nothing but Diagnostics and Feedback data that Windows collects and sends back to Microsoft. Moreover, the recommendations are only visible if you are connected to the internet, else it will show the same message.

intel's first gaming card that will hit the market soon has been shown in its innovation event, the Intel Arc A770. In its core ticks ACM-G10, coming with 32 Xe-cores and all the way up to 16GB of GDDR6 memory (the basic entry-level version will have 8GB of GDDR6). The card will support ray tracing and supersampling with Intel's XeSS.

This is Intel's first gaming desktop GPU and after testing with some YouTube channels it turned out that the card itself sits somewhere between nVIDIA RTX 3060 Ti and an RTX 3070 so it will still be low in performance compared with the new RTX 4090 or AMD's new RDNA3 upcoming lineup. But as stated this is Intel's first gaming graphics card and having this kind of performance is no small feat for the first-time product.

One thing that is really great tho and that is going for Arc A770 GPU is its price! The Limited Edition card will cost $329 which is at this moment most cheapest GPU currently on the market in that performance range. nVIDIA is between $500 and $700 for comparison and if Intel can hold on to its performance with almost half the price card could be a great hit among gamers. GPU itself will launch on October 12th.

Also for anyone interested desk itself comes also with RGB lights for that true gaming feel.

Cyclic Redundancy Check Error - What is it?

To begin with, Cyclic Redundancy Check is basically an error checking technique. This technique is used for data verification. It detects accidental changes in the data. It is used by computers to specifically check the data stored in the hard drive or optical disks (DVD’s and CD’s). The Cyclic Redundancy Check error occurs when the data being verified on the hard drive or optical disks is corrupt. Symptoms for this error code include program lock-ups, slow PC performance, inability to run and execute the desired program, system freeze and shutdown and startup issues.

Error Causes

The Cyclic Redundancy Check error code occurs due to the following reasons:

• Cluttered hard disk
• Registry corruption
• Misconfigured files
• Unsuccessful program installation

All these causes points towards registry issues and poor PC maintenance. The registry is the main database of the computer. This part of the PC saves practically every activity you perform on it including activities like application installation and deletion and web browsing to name a few. With time and frequent PC usage, the files generated from every activity you execute on your system begin to load the registry. These include even the unnecessary files like junk files, internet files and files of applications that you’ve uninstalled. All these files overload the registry and acquire a lot of hard disk space. And when you don’t remove these files on your system, eventually it leads to file misconfiguration, cluttered disk, and registry corruption. New program versions that you want to install and run on your system also don’t function because the files of the old program version still saved in the registry.

Further Information and Manual Repair

As the Cyclic Redundancy Check Error causes data corruption on the hard disk, it is advisable to fix this error right away. The reason is that it can have serious consequences. It can lead to data loss, fatal crashes, and system failures. When it comes to resolving Cyclic Redundancy Check Error, there are two ways to fix it:

Run the CHKDSK application.

This is a built-in feature in your Windows system. It checks for hard disk damage and attempts to resolve it.

Recently, some users reported not being able to boot up their Windows 10 computers. And during the startup phase, at some time, the bootup sequence is halted with a Recovery error along with an error message saying, “Your PC/Device needs to be repaired” with an error code of 0x0000605. This kind of error message indicates that Windows was not able to verify the digital signature for the file as the signing certificate or it could be that it has expired. To resolve this error, you can follow the potential fixes given below and see if you stumble upon a fix that might work out for you.

Option 1 – Change the Date & Time settings in the BIOS

Some users reported that they were able to fix the error by changing the Date & Time settings in the BIOS. Upon checking, they saw that in their BIOS settings, the date was off several years. As a result, the incorrect date and time settings end up ticking the system into believing that the Windows build has expired long before the actual expiration date. You can check if the error pops up due to the same reasons by accessing the BIOS settings. To do so, you have to tap the Boot key that’s associated with your motherboard manufacturer during the initial startup phase. After that, you can search for a particular boot key online or you can also tap keys like F2, F4, F8, F10, F12, and the Delete key. Once you’re able to access the BIOS settings, locate the Date & time or anything similar, and then check if the date is correct or not. If not, you need to change the date to the actual date and then save the changes made and restart your computer and then check if the issue is now fixed or not. Just remember that if the actual date is past the expiration date of the build you have, you need to change it to an older date. If your Windows 10 PC is able to boot back up, you have to update it to a stable Windows build and then go back to the BIOS settings and change the date to the current one else you will definitely encounter Windows update errors in the future as well as security alerts.

Option 2 – Perform a clean install of a stable Windows 10 build

If every system boot fails accompanied by a BSOD error with error code 0x0000605 “A component of the operating system has expired” and you’ve already followed every instruction on option 1, then it’s most likely that your current Windows build has already expired. Remember that almost all the Windows 10 Insider Preview builds (98xx) are created along with an expiration date and when your computer reaches the expiration date, you won’t be able to boot your computer up. Note that the exact expiration date varies based on the build number. And prior to the expiration date, the operating system will start to display some error warnings telling you that the build will expire and urge you to update the most recent build available. And so once the computer reaches its expiration date, it will begin to reboot every three hours until it no longer boots up which is about 2 weeks approximately after the license has expired. Once the expiration date is up and your computer no longer boots up, you need to perform a clean install and then install the latest Windows 10 build to resolve the issue once and for all.
