When I converted from Win 98 to Win 2k, I experienced a major problem when running direct3d or opengl games or applications. For example, when I run 3d Mark 2000, sometimes half way through the testing, a blue screen of death will appear, with an error message:

***STOP:0x0000001E (0xc0000005, 0xBCA6E379, 0x00000000, 0x3f1999B1) KMODE_EXCEPTION_NOT_HANDLED
***Address BCA6E379 base at BCA39000, DateStamp 3a076179 - nv4_disp.dll
Beginning dump of physical memory
Physical memory dump complete. Contact your system administrator or technical support group.

When I run games like Half Life: Counterstrike & Quake 3 Arena, I get the same problem & the same error message about after half an hour of gaming.
I've installed Directx 8 final, Detonator 7.17 drivers, AGP 4-in-1 drivers, the patch posted by Microsoft, & absolutely everything that Geforce FAQ could suggest.
I still get the problem no matter what drivers I use (6.18, 6.31, 6.34, 6.47, 7.17)
& no matter whether I use Directx 7 or Directx 8. The problem never goes away.
I need help here!!! Here's my system specs:

AMD Athlon 700mhz
Creative Gefore Pro (DDR)
Kingston PC100 256 mb ram
Sound Blaster Live! Player
Maxtor Diamond 20.4 7,200 rpm hdd
MSI K7Pro mainboard
& the rest ain't important...

I need help! Please respond!!!

I have a very similar system:
AMD Athlon 750 MHz
Hercules GeForce 2 MX
PC133 128 mb ram
Sound Blaster Live! Player
Maxtor Diamond 20.4 7,200 rpm hdd
ABit KA7-100 mainboard

Win2k and games run fine, as long as fast writes are disabled in my BIOS. With fast writes enabled the system crashes after playing a game for like 3 minutes.

Try updating your motherboard BIOS.
But since you've said that you've done everything in the GeForce FAQ I think you may be out of ideas. Have you tried this new AGP VIA fix?

Chipmunk,

You are OVERBLOATING the situation.

First; you NEED to turn AGP down to 1x (Use powerstrip or go to www.geforcefaq.com and download a regfix)

Second, turn fastwrite OFF

Third, GET NEW FUCKING DISPLAY DRIVERS

nv4disp.dll or whatever that blue screen of death error was, was caused by your graphics drivers.

Click HERE and get the OFFICIAL Det. 3 drivers; this will solve your problem.

I'm almost sure of it.
Hope this helps
