Diamond ATI 3870 crossfire driver crash windows XP x64

[mcardo]

Asus P5E
Intel Q6600
4GB Corsair Dominator
2 x Diamond HD3870 512MB with Catalyst 9.11
Windows XP x64

While I'm using windows, at random times (still haven't figured out a pattern to the crash), the screen freezes, the mouse still works but anything I click on will not respond, eventually the screen goes off and after 5-10 secs it usually comes back on with an ATI message stating that the video driver has just recovered with the option to send a report. Half the times after the screen goes off the driver will not recover having to restart my machine.

Has anyone experienced this?
Any solutions?

Thanks!

One or both of the cards could be over heating but since you did mention any thing about overlcoking I assume that you are not at this time. First check the cards for any major dust build up and test them separately to rull out a dud. Make sure that your psu is good enough or not failing.

Thanks for the reply. Cranked down the Core and memory frequency a notch and haven't gotten any other instances of the error. I had overclocked the core about 80 Mhz over.

Thanks!
