system shut-down

[geo22]

i am not sure if this is the right forum or section in this forum
i built my computer just after xmas

ASUS M5A99X Evo
AMD Phenom II X4 965 Black
XFX Radeon HD 6850 Fansink 775MHZ 1GB
Western Digital Caviar Black 500 gb
Corsair TX750
G.SKILL Ripjaws X F3-12800CL9D-8GBXL 8GB 2X4GB
Zalman Z9 Plus

it will occasionally shut down it can just be idleing like i might have a couple web browsres open and then minimumized at the bottom and it might be sitting like that all day then it will just shut down if you try to use it. but not always sometimes after sitting that long it will just work normally. it does not do this that often. but i have noticed it will not let me access the bios. if i tap the delete during startup it will not go to bios it just sits blank screen. i have tried just taping delete a few times same thing it will not go to bios it just sits with blank screen. if i start it up touching nothing it starts normally any suggestions

ive only built a few rigs so im no pro but i would try it with 1 stick of ram at a time and see how it acts,Maybe it goes into sleep mode and wakes up cranky LOL

I think you may need to reset the bios. just make sure you unplug the powercord from the PSU before you do.
