It all started yesterday when I went to install a new eSATA drive. I updated the BIOS from 2692, which i've been running for ages, to the latest 2809. Reason being i was going to enable the Marvell controller, for which serveral things had been fixed (s3 resume etc). BIOS upgrade went ok.
Marvell controller installed in Vista x64 ok, eSATA drive worked fine. But then it started crashing - instant reboot, nothing logged in the windows logs, no blue screen (auto reboot is disabled).
Assumed it was the marvell or eSATA disk so uninstalled both and disabled the marvel again. Still crashed. Went back to BIOS 2692. Still crashed.
I've reset bios defaults, unplugged everthing unessential, voltages appear fine. I also ran the MS RAM test and that showed no erros - also tried MemTest86 3.4 which locks up on one of the tests (about the third one). I tried underclocking the RAM, tried each of my RAM 4x 1GB modules seperatly. Nothing made any difference.
The reason for the eSATA drive was to backup my RAID0 array which has been failing occasionally (comes back after a reboot) - I suspect thats due to me not disabling TLER on my Western Digital RE2's.
I'm now thinking duff board? Will phone Intel tomorrow.
Does anyone have any sugesstions?
