DFI Infinity 975g/x problems

After reading on a different forum I heard that the DFI bios from 11/15/06 would greatly inprove overclocking potential, note; this was a beta bios and I downloaded it and tried it and within a few moments the system was running at 3.43GHz and (previous best was a unstable 3.17GHz) ram at a 1:1 devider runing at 761 MHz cas 4, voltage at 1.4v and I had managed to get it to ~3.62GHz before full load temps started making me nerivous (two instances of CPU burn in, temps of about 65 C) decided to put it back down to 3.43GHz but I changed the memory devider, im not sure what it was but the last known ram frequency was about 950MHz. then it seem to load, (stared, went through the mem test, rocognized the drives) then as usual i saw the message "verifying DMI pool data" or something like this, then it froze for a few minutes, i got impatien and reset it. the nothing happened, the computer will turn on, (lights glow, fans spin, drives start) but the screen shows nothing and then falls into sleep mode. From what i've seen in other threads i would guess that the mother board it shot. Any ideas?

System specs
intel e6600

DFI Infinity 975g/x
EVGA 7950 gx2
WD 320gig 7200.10 hard drive

Thanks for any input.
PS Does anyone know about the DFI warrenty and customer service?

Maybe because you spelt it wrong.. its 975X/G and not 975G/X.
If i was a motherboard and you mispelled my name, i would refuse to boot as well!

Seriously now, it could be anything, RAMs, too much voltage on the Northbridge... etc etc. Try to remove components to isolate the problem before you jump on conclusions.

Good luck friend
