need HELP with video crashing system


A recently installed NASCAR 4 game has been locking up my system after about twenty minutes of play. In an effort to fix this, I updated with the win2k6011 driver then rebooted. I made a few changes to my Radeon 32 DDR with UniTuner based upon a tweaking article found at and rebooted. I can run NASCAR 4 at 800x600 16 bit with all effects set a minimum which is very unrealistic and boring. 3DMark 2001 causes the system to automatically reboot after the first demo test completes. The system log has the following error message recorded:

“The computer has rebooted from a bugcheck. The bugcheck was: 0x0000001e (0xc0000005, 0xb78a2b71, 0x00000000, 0x00000008). Microsoft Windows 2000 [v15.2195]. A dump was saved in: C:\WINNT\Minidump\Mini011302-01.dmp.”

Determining that the previous operation was better than the present, I decided to try to get back to the initial setup. The instructions for the latest ATI driver says to uninstall current driver with the add/remove programs utility before loading the new driver. The utility will not remove the Omega driver because it is not “certified”. I tried loading the ATI driver anyway; however, a look into the registry has the following text which seems to indicate that Omega driver is still installed.

ATI Radeon 7200 (Omega 2k 1.0.86) (0x00000000)
System\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000 (0x00000000)
ati2dvag.dll (0x00000000)
SYSTEM\CURRENTCONTROLSET\ENUM\PCI\VEN_1002&DEV_5144&SUBSYS_00BA1002&REV_00\4&618BA55&0&0008 (0x00000000)
C:\WINNT\Inf\oem0.inf (0x00000000)

ATI Technologies Inc. (Opt. by Omegadrive) (0x00000000)
D700-0110092300 (0x00000000)

I need help.
How can I remove the Omega driver?
How do I get back to stock video settings without a reformat and system rebuild?
What is the bugcheck error that is crashing the system?

  1. You'll probably have to manually delete the entry from the registry, but I wouldn't do this without:

    1. Backing up existing registry
    2. Seeking more experienced registry hackers!

    Oh go ye brown-eyed toothless wonder.
