Reader Question:
“Hi Wally, My computer has been restarting since I installed a graphics card in my computer. The graphics card was working on another computer so I don’t know why its not working in mine. The error code is “ AGP ILLEGALLY REPROGRAMMED “. I think its a problem with Windows. How do I fix it? Thank You.“ - Eric L., Australia

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: The AGP Illegally Reprogrammed error is really annoying because it causes problems with graphics cards. If you’ve encountered this blue screen error for the first time, you are probably not very sure about what to do next. These errors can seem pretty difficult to solve at first, but you can fix this problem relatively easily when you know what to do.

Problem

The AGP Illegally Reprogrammed or STOP 0×00000106 error appears and the computer restarts.

Cause

The AGP Illegally Reprogrammed error appears when the AGP port is reprogrammed incorrectly. This is usually the result of a bug in the device driver of the graphics card. The device driver may have been corrupt or outdated. Unsigned drivers can cause these problems.

Solution

Here are some ways to fix the AGP Illegally Reprogrammed error:

Is Your Driver Compatible With The Driver?

You can find this information by going to the Windows device manager. Here’s how to do it:

Press Windows Key + X and click Device Manager.
Make each category Expand by clicking its arrow.
Look for a yellow triangle or a red mark. A yellow mark tells you that the driver is not working. A red mark usually means that the hardware itself is either not connected properly or that it is damaged.

Update Drivers To Fix This Error

If you see a yellow triangle next to an icon, you should try reinstalling its device driver. Download the latest version of the driver from the internet and install it manually, or upgrade the driver using a driver utility like DriverDoc.

In case of a red mark, make sure that the device is properly connected to the motherboard. Also, make sure that the device is compatible with your computer’s hardware.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing!
