The best way to beat the error is to install the latest official release directly from the manufacturer’s website.

So, visit any of the following sites to download compatible drivers:
If they come as an archive file, likeZIPorRAR, extract the executable software in a separate directory.

Hit theClean and restartbutton to remove the video driver completely, eventemporary files,cache files, andregistry entries.
Once you’re back on theDesktop, go to theDownloadsdirectory and install the recently downloaded AGP driver.
Remove Any Newly Installed Hardware
If the above methods didn’t fix the problem, the BSOD error might be linked to a newly installed AGP, RAM, or other internal component. This method only applies to desktop PCs:
The new hardware you installed is compatible with your PC system if the issue doesn’t reappear. In that case, look for suitable replacements to resolve AGP_ILLEGALLY_REPROGRAMMED.
You can also follow this method to remove and re-install your existing components. This often helps fix the BSOD error.
Disable Fast Startup
Turning off the fast startup mode usually resolves this error. Here are the steps to follow:
Run the Microsoft Safety Scanner Tool
Microsoft Safety Scanneris a free malware detection and removal software from Microsoft. To use it:
Clean Boot the PC
In the Clean Boot state, Windows OS only runs Microsoft services andbackground processes. So, this is the best technique to isolate any third-party software causing the AGP_ILLEGALLY_REPROGRAMMED error.
Restore PC
Try restoring the PC to its last known good configuration. This method is only applicable if you’ve enabled the System Restore Point creation feature.
By default, Windows OS automatically creates a system snapshot when you make substantial changes, like installing a driver, software, etc.
Your PC will restart a few times during the process. Once it’s back on the Desktop, keep doing what you were previously doing when the BSOD error showed up. Monitor the system for a few hours.
Replace AGP Card
The AGP hardware is likely broken or its chip isn’t working as it should. The embedded circuitry is trying to modify the built-in programming on its own due to electronic faults.
If someone you know is also using the same AGP, you can borrow it from them, install it, and see if the issue goes away.
If it does, buy a new AGP.
Contact Manufacturer for Warranty Services
Most AGP cards come with a3-year warranty period. So, you should check with the manufacturer’s support team if you can get a replacement or repair service. Here are the support portals for major AGP manufacturers:
For laptops and brand-sold desktops, it’s better to contact the customer support team of device manufacturers, likeDell,HP,Acer,Lenovo,Asus,MSI, and so on.
