Hi everyone.
Today i found out my computer will suddenly shut down everytime after playing bf3 for 5 min.Then when i tried to start it up, everything started working then shut down again. I need wait for 1min or unplug the power to get it working and go into windows. Then i wonder if i overclocked the cpu too much causing the overheat. Then i found out i cant access to BIOS now, everytime i hit delete button, the computer shuts down. I built the computer 3days ago. works fine in the first 2 days. Please help me

system:
cpu: X4 955
mobo:Asus m5a99x evo
graphic cards: gigabyte Radeon hd 7850 2gb, His hd 7850 2gb
RAM:8gb Gskill
PSU corsair gs 800

Hello, are you using ONE stick of 8 GB ram? If you are the mobo you have can't support any ONE stick of ram exceeding 4 GB. To fix you will have to buy TWO sticks of 4 GB ram. Sorry for caps, lol.

I'm pretty sure that Motherboard can handle 32Gb of RAM, and if my math is still correct and valid (might have changed in the late years xd), 8x4=32...
