cpu problem?

[rashers52]

been getting random shutdowns recently.

when i try boot back up the light on the motherboard (asus rampage 3 extreme) stays on cpu and wont move on to the next light. nothing loads up not even the post message.

to get past this i have to press the clear CMOS button atleast twice.
i only really notice it when it shutsdown is when i click on something like a link.

is this a cpu problem or could it be psu ? i have a corsair HX850 psu

i have a RMA number for the motherboard and cpu , but obviously i dont want to send it off if its still working :s

bios is flashed to the most updated.

im currently running the RAM higher than what it was set to as i wasnt even reaching 1000mhz , seeing as i have a set of 2000MHz.

other than that everything is at stock speed

ive tried using just 1 gfx card and ram. no beeps just LED lights. when theres a problem the light hangs on CPU. and wont move onto the next LED. should i just send it off as RMA (cpu & mobo)?

yes i have reseatted the cpu , checked for bent socket pins also. cpu cooler is fine on the cpu. all my specs are listed in my 1st post. do u think maybe a windows update is causing the problem or a copied version of windows ?? it has been fine for a few weeks since i built it , then about last week its been a pain.
