Windows Cannot Be Run Even in Safe Mode Hanging on agp440.sys File

Today, I was working on a computer with the following problem:

Computer suddenly gets restarted and it never can run into the windows anymore. After Windows loading screen, it again get restarted without any more information.

At the first I tried to run the Windows into the safe mode. but the following problem happened:

Windows hangs in loading agp440.sys file.

After some searching on the Internet I found the problem is about the graphic card driver conflicting the windows. So you have to do it disable this driver. To do so:

1. Insert Windows CD into the drive and restart the computer.
2. When asking you "Press any key to boot from CD or DVD...", press any key to load Windows setup screen.
3. Press R to load the recovery console.
4. Press 1 and press enter -If you have more than one windows installed, press the one having this problem.
5. Enter the Windows Administrator password. (Even if the your Administrator has no password, it asks you for that, just press enter to pass it.
   
6. type listsvc to list all services on your windows, make sure the agp440 is listed.
7. type disable agp440 to disable this service.
8. type exit and your computer gets restarted.

Now hopefully your windows can run without any problem, but one thing that you might notice is the resolution of Windows is 640x480 and with low color depth. Just change it to your desire resolution.
