need HELp with video crashing system

[sys-eng]

01-13-2002

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 http://www.rage3d.com/radeon/reg/index.shtml 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.

HKEY_LOCAL_MACHINE

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?

For just a quick reply, you may have to go into the registry w/Regedit32, drill down to the lowest level keys you wish to delete, click "permissions", and add "administrator" for full control. Only then can you delete certain \enum keys. However, you must be certain of what you're doing. Also, the indicated .inf file needs to be copied somewhere else for backup, then deleted in the .inf folder. Be very, very careful deleting video devices as this might prevent you from booting.

Well, I am not certain so that is why I am seeking help. I do not know what to delete without causing catastrophic harm.

I really messed up when I violated my policy of not loading anything that did not have a uninstall feature.

Thanks for the reply.
