Hey Guys, I have a really strange issue that hopefully someone can help me with.

The problem started last night where after running the system for over 3 weeks completely stable, it just rebooted and the board flashed my bios to 0602. I was previously on 0903 and didn't realize the board flashed the bios, so the system was completely instable afterwards. I flashed the bios to 0907, played some cod4, everything seemed ok. Then I decided to run prime overnight and this morning I found the system to have rebooted with the bios flashed back to 0602.

What would be some reasons for the instability to happen all of a sudden??

Here are my settings:

FSB:450
Mulitplier:8
vcore: 1.39
vpll: 1.6
Boot Strap: 333mhz
Dram: 1086 @ 5-5-5-15
command: 2T
Vfsbt: 1.52
vnb: 1.63 (using 4gig of ballistix 8500)
vdram: 2.13
transaction booster: disabled
dram static read: enabled

My previous settings when it was 3+ weeks stable was the same as above but with a vdram of 2.04 (2.1 actual).

I'm just looking for a few suggestions to try tonight, since I'm at work atm..
