I've spent the last 2 hours to install a fresh copy of my Windows 7 Pro 64, drivers, and tools. From scratch. It's really quick with SSDs and I have a burn proof process to shorten a full installation on existing system. Well fresh installation.

And yes guess what:

> Stalker benchmark is running perfectly, 4 pass in Ultra mode Direct X11 @ 1920x1200... 3D Mark Vantage is running perfectly

Well I didn't test Cod4 nore PC Mark vantage again but... it seems to be fixed now after this fresh installation. Yes... I choosed fresh installation instead of time consuming troubleshooting!

Now here is the list of potential provoking components, because as explained I did not have these problems some days ago, so I tried to summarize what changed on my system the last 2 days:

> installation of MSi Afterburner
> activation of ATI CCC Overdrive functionnality (I clicked on the lock)
> I tried to use the Autotune functionnality of the CCC Overdrive menu, but after 30 minutes... I decided to leave this ''auto tune'' tool because nothing new happened... and I have restarted the system to make sure the clock has been reseted (as recommended in the CCC message after closing the auto tune)
> I tried some times to activate the Eyefinity feature, I succeded but each time the final result was a bug or a system crash
> installation of 3D Mark Vantage and PC Mark Vantage (shareware license version)
> uninstallation of ATI driver ''8.663.1_Beta5_Hemlock_VistaWin7_Nov11.exe'' and installation of ''ati_vista_win7_hemlock-xt_8.663_oct28'' following recommendations from the XFX support
> during uninstall of ATI driver, black screen... manual system reboot, and I finished ATI uninstallation after this reboot. Maybe something happened in the registry or dll's or something... but problems appeared BEFORE this issue with driver change happened

And... well that's all I can remember and that MAY have corrupted the system stability.

Concerning your request Alous: I HAVE NEVER overclocked my HD5970, only 1 time tried to use this f*** CCC Autotune... but didn't work, and finally I never ran my HD5970 under OC. Never. For your Crysis request, I suppose that there will be no difference compared with STALKER benchmark, I mean using this Benchmark loads both GPU's @ 99%, using Furmark with MSAA x8, full resolution xtreme load with both GPU @ 99%... seems to be an extreme situation. And now under stress situation, my card is not locking my system anymore... after the fresh installation of Windows and drivers. But anyway if you want I can run a Crysis benchmark, do you have a link? I don't play this game so I don't have it in my collection.

The reinstallation of the ATI driver was probably not a good idea, something was probably still corrupted within the system... I don't know what.

If the next test I'll do are ok, and if the system does not crash anymore... it's clearly a driver issue, and what's exactly the provoking component... hey hey good question. I'll give you an update soon. Great to learn that ATi will update the driver soon.
