explorer.exe crash hours after boot, BSOD after days

[ShadesOfMarble]

Using an AX1200, P8P67 WS Board, Windows 7 32-bit, Cat 12.2pre and latest cgminer with 2x5850/5870/7970 I'm experiencing a strange problem:

- 1-2 hours after booting the system, explorer.exe crashes (".. is no longer working and needs to be resarted"). Eventlog says crash in explorer.exe/shell32.dll, exception code 0xc0000005.

- after 7-10 days, the system resets with a bluescreen, errorcode 0x0000007e.

This has now happend two times.

The system ran fine for months(!) without reboot, but then I replaced one dead card with the 7970, installed 12.2pre (was using 11.8 before) and fiddled around with memclocks. I restored the memclocks to stock settings for now and replaced the RAM...

Wondering if anyone has experienced something similar and can give me a hint?

I found 12.x series drivers and 58x0 cards really dont go together well, if you drop the 7970 out and go back to 11.11 drivers does the system become stable?

I don't know (yet) Can I just reinstall 11.11 and leave the SDK alone or do I also need to remove the SDK (by hand)?

Of course, it's always microsoft failing... can't be AMD, because their drivers are always perfect </IRONY>

Reinstall windows bro.  Not that hard.  Get a fresh set of files.
