Serious 9500 Pro Driver Problems

Well, i've been battling thing probelm for about 4 hours now, to no avail. Bascially this morning when i woke up, i was browsing AT when all of a sudden eveything freezes up. After reboot, another freeze. Works in safe mode though. So I go into safe mode, everything looks okay, so i try to boot into regular mode again. Gets to windows this time, but at 640x480 with no indication of a 9500 installed. So i go to reinstall the drivers. Seems to work, but when i get back to windows, anytime i try to go about 640x480 I get an infinite loop in ati2vag.dll - The card has the origonal clock speed and bios. System is a TH7-II with a 1.6a@2.133. Never had any problems with my visiontek Geforece3 class.

Guess i get the anti-ATI myth now. Anyway, anyone got any suggestions (I've tried the Cat 2.3's, 2.4's and 3.0's - always the same problem). Thanks.

Did you just put this in after removing the GF3 ? I have read many times here that you need to do a clean install after changing from Nvidia card to ATI. Have you done that ? I wouldn't blame it on the drivers YET. You are heading for a flame war here.
 
The ATI card was installed on a clean install of WinXP - no trace of nVidia anywhere. Everything was running fine until the sudden lock up.
 
OK, next, have you tried running at stock speed ? How long was it running before you had the problem ?

Edit: Oh, and have you tried it with the case cover off ? (overheating ????)
 
What is the agp bus at? Have you tried running your comp at 1.6? ATI cards are known to be finicky(sp?) when it comes to overclocking the agp bus.
 
I've got the case cover off right now. The 1.6GHz -> 2.133GHz OC has been stable for about a year now.. never any problems at all. It's at a 133MHz bus, so the AGP and PCI speeds are all at stock. The system was running fine with the 9500 since about Christmas. Now all of a sudden this. The BSOD says the infinite loop is commonly caused by a hardware problem, but it could be drivers. Gonna be really ticked if this is a hardware problem, but reinstalling the drivers (even after a complete sweet of the inf's and registry) doesn't seem to have any effect. If i leave it on the default VGA driver I can change resolutions at will up to 1280x1024. Obviously that is not solution, however. Thanks for any suggestions... guess I'll try it at 1.6Ghz now, but I have a feeling that won't do a thing.
 
maybe you got a dud

i would try for an exchange if possible

also try turning off write combining, fast rewrites, and set AGP to 2x

also what is your AGP Bus set to

is it locked?

if so i would try setting the AGP Divider to 1/2

IMO the lock settings dont work very well at all

also see if anything is sharing an IRQ with the GFX card

i think for the TH7 II it is either the first PCI slot or the last though i cant remember off the top of my head but you should populate those 2 slots last if you need them because i have this motherboard as well
 
Turing off write combining seems to have worked for now, paired with fresh Cat 3's. What am I losing by having write combining off?
