I bought an entirely new setup at the end of last year consisting of ...
Antec 1200 tower case
intel core i7 930
gigabte ga x58 ud3r rev2
corsair h70
corsair hx850
corsair 2000mhz 6gb
xfx hd 5870 radeon xxx edition
Windows 7 64bit Ultimate
And I've had no end of problems with BSOD and GSOD (Grey/Green stripes of death, basically you get vertical stripe lines and your computer completey hard locks, you can not even ctrl-alt-del!) crashes and it's driving me insane, I've tried so many things to try and make some kind of difference, so far they consist of:
*Flashed the card to the latest bios on the xfx support site
*Installed and tried every ati driver release from the xfx site from 10.10 onwards and used driver sweeper on each occasion to make sure all remnants of the old drivers were removed.
*Memtestx86'd passes 100% after 1 full pass
*Removed all traces of gigabyte DES2 energy saving and it's realted grdv.sys driver that can apparently causes crashes on gigabyte motherboards with setups requiring a lot of power
*Running Microsoft driver verifier
*Updating all my motherboard drivers
*I'm running my harddrive in AHCI mode not RAID or IDE
*My memory/cpu is running at totally normal, not over clocked settings
What I have noticed is:
*Only intensive games like half life 2, left 4 dead 1/2, civilisation V, settlers 7, battlefield 2 bad company. gta iv (i.e. not older games) and benchmarking like furmark seem to make it crash
*BSOD's with memory.dmp dump files always return...
Unable to load image \SystemRoot\System32\drivers\dxgkrnl.sys, Win32 error 0n2 BugCheck 116, {fffffa80057164e0, fffff8800492e008, 0, 2}
Probably caused by : atikmpag.sys ( atikmpag+7008 )
Followup: MachineOwner ---------
I have a log of crash dumps if anyone wants more info.
*GSOD's with a complete hard lock as well as artifacts and GSOD's that recover momentarily before later fully hard locking, black screens for 10-15 seconds then a recovery.... all of which can happen anywhere between 10 minutes or 4-6 hours!
*The temperatures in the case are not much higher than ambient, and the card gets to 60-70 at the very most. The case and cpu together have 8 fans!
*Turning my virus checker off seems to "help" (i.e. prolong the length of operation) but not remove the problem (i.e. it still eventually crashes!)
*The stripped crash (GSOD) has never occured when "not" in games or benchmarking, so just fiddling around on the internet is fine.
I'm now at the point of considering asking for an RMA from scan, but I'd like to know if anyone can think of anything else I could try?
