Hey everyone, I got this weird issue.

The pc will load ill hit del to enter setup and about 30 secs later the system just shuts off????

the best way to solve this is the process of elimination. but before u try that, just a couple of things,

try using a popular brand stick of ram if u got any
reset cmos (refer to manual)
check the sticker on the psu, and tell us how many amps (XXA) it has in the 12v rail(s)

but i have a suspicion ur mobo could be shorting out, maybe a loose screw or standoff etc.

sounds like you're not getting enough power (probably to your GPUs)... try with only one GPU, one DIMM, CPU and HSF (no HDDs, opticals or anything else) and see if you can get into the BIOS

What PSU do you have?
