Insert the system repair disk in the A drive and boot the system,select to start in safe mode,proceed to trouble shoot.
Check the Device Mananger and check the video driver and update the driver.Hope this can get you started

Sorry I couldn't be more help but I ran across this last week and it really sucked.

The bootlog idea in answer 2 is a good start. Windows protection errors can have a lot of causes, however. Check out Microsoft Knowledge Base Article Q149962 "Troubleshooting Windows Protection Errors"

What version of windows are you using? Also if you are using a AMD CPU 350Mhz or higher with Windows95B or C you can get a patch from Microsoft at http://www.microsoft.com/windows95/downloads/contents/WURecommended/S_WUServicePacks/AMDPatch/Default.asp this will correct the issue. If you have Windows95A there is no patch but you can correct the issue by underclocking the CPU. This is if you have a AMD CPU 350Mhz or higher.

You don?t give us much info but check in the
BIOS whether an IRQ is assigned to VGA.

If yes, Change the graphic adapter to standard VGA, de-install your card?s drivers,
install any AGP drivers for your MB?s chipset, install DirectX 7.x, re-install your
GFX card.
