i recently replaced a x1950xt card w/ a visiontek hd3870 card. since i replaced it, my computer freezes up when playing games usually after about 30 minutes of playing. i only play racing games so they are not super demanding. i'm getting over 100fps at all times w/ the settings i'm using, so i'm not over working the card, and the temps are never going over 70c.

i've tried installing various versions of ati's ccc, and am currently not using it at all, after removing it and using a registry cleaner to clean up after it. all i have now is the driver and rivatuner to control the fan, and it still does the same thing, although it does seem to take a little longer for it to happen now.

any ideas?

what do you have the fan set at should be no less than 60%

i'm using a progressive fan speed to temp setup:

fan speed/temp
40% @ 45-55
50% @ 56-60
60% @ 61-65
70% @ 66-70 <= while racing it tends to sit here, right at about 68-69 degrees
80% @ 71-75
90% @ 76-80
100%@ 81-100

What's the power supply?

actually nevermind, the 3870 should draw less power than the x1950xt that thing was a beast.
