I've been getting very similar crashes ever since getting my xfx 5870. I had absolutely no stability problems when I had my 8800gt, but now I'm constantly holding my breath waiting for another hard lock. The card works fine in games, never locks up or anything, it just crashes when coming out of sleep when I log in. sometimes the driver can be reset, other times I just get a black screen. If I'm lucky I get the "display driver has stopped working" dialog and then it's ok. Nothing is overclocked and it did the same thing in vista64/win7 64 beta/win7 64 rtm. My guess is it will go away if I shut down every time or don't put it to sleep, but wtf kinda crap is that!

Last week I come to mky system to find it with a blank screen and it wouldn't respond. It tried to boot up with 3 quick flickers of the power light and then went ttally dead. I pulled the CMOS battery and it came back and run for 8 days but did crash several times. It crashed 5 times yesterday and I realized Win 7 was running in there but I couldn't see it. I finised it off today with several restarts trying everything I could. I put my 4870 back in and i;m back to normal. well except for the $400 hole in my pocket and I try not to think when I will see it again : ( Played Dirt 2 three or four times : (
I posted my problem to XFX support last night. No word today and I replied to them it wqas dead. Still waiting. I got it 11/2 at Micro Center so my 30 days justslipped by. They don't have it anyway.
My 4870 did the same thing. Now I am tracing the problem back to ASUS BIOS 1805 I flashed on 11/25. I've had crashes ever since. I tried to back up as I have before but any older BIOS errors out with "File date older than board" After I reset the CMOS it goes back to '02. How can any BIOS dated xx/09 be older? ASUS has hosed my motherboard. Back to Gigabyte GA-X58A-UD7. I just don't like having to water cool the chipset. No biggie cuz I have the whole setup from my first GA-EX58 that blew 2 video cards. I'm just not having a real good year with my i7, m/boards and video cards
It seems if I turn off "ATI Overdrive"it will go further. I had forgotten to disable the PCIE Spread Spectrum in BIOS so that's fixed now. Here I sit typing waiting for click - blank.
What does PCIE Spread Spectrum do and why disable it? Don't think I have messed with that one.

I ddn't pay $400 for my 5870 t get it replaed wth a 5770.
I replied to XFXForce that a comparable card wasn't acceptable as a replacement for my 42 day old $400 video card. I haved heard back yet as it wasa Friday late when I sent my reply in.
