What would cause a 64mb GF3 Ti500 to lock up during 3DMark2001's high resolution tests. I've run each test separately and determined that the card freaks out (locks up and goes black, sometimes weird colors are displayed) when the high res car chase, dragothic and lobby tests start. Each of the other tests run smooth and produce some good FPS. The card originally came from a Compaq Presario. I'm using Nvidia 61.77 drivers, DirectX 9.0c, WinXP SP2. I've tried this card on three other computers with the same software setup...similar hardware configurations(2.8P4, 512 DDR pc2700). The freeze up occurs on each machine. The only game I've tried was MidnightClub2. It crashed as I started actually playing, not in the menus...
I hope I don't have to trash the card!! Thanks for your time!

Crashman- Thanks for the reply. One of the first things I did when I saw the problem was to check to see if the fan was spinning...and it was. Should the fan spin at higher rev's to match the strain on the GPU?
Do you think it's worth taking the fan off and applying a different compound, like artic silver, etc...?
Could be that the fan is not spinning fast enough. have you notices any snowing or artifacts in other graphic games. Can you touch the HSF without bruning your fingers? Could unplug the fan and have a good case fan blowing on the HSF of the card to see if it is stable.
Also get MBM5 and monitor for voltage rails and make sure it does not deviate +-5%.

You could try underclocking the core and memory. If it's fine clocked way down, it is a heat issue. Then raise the memory back up a little at a time and run some tests. If mem gets back to normal, do the same for the core until problems come back. Anyway, a new heatsink/fan or resetiing yours with good thermal paste may help cool things down. Or you could get one of those bracket fans that internally blows on the video card.

Thanks for the advise guys, I'm headed to the airport in a couple hrs so I'll have to look into it further when I get back...prob shouldn't have asked about the issue until I got back. But, I do have some hope that I won't have to trash the card.
Thanks again all and I'll post back when I've had a chance to mess with it this weekend.
