Alright so i assemble my computer about 3-4 days ago. And at first everything was working completely fine. But today i left my computer on for an extended amount of time 9-10 hours just sitting there on my desktop. When i came back the screen was completely frozen, so i turned off my pc. Then my pc booted itself up again and immediately turned itself off, it would repeat this process 3-5 times, Until it would finally let me go into windows. Sometimes when i get to the window desktop it would freeze again or shut itself down again, and the same process would repeat. Everything in my pc is practically new. Here are my spec.
MOBO:Asus p9x79 WS
GPU: 2x 780ti's
CPU: intel i7 4930k
PSU: Corsair AX1200i
Ram: Corsair platinum 16gb 2400mhz (4x4gb)
OS: window 8.1 64 bit.
Cooling system: Corsair H80i
Like I've said all components are practically new, the oldest component would be my gpu which is less then a month old. Any idea why it's acting this way?
 


I'm not quite sure what you have asked me. If i start the system with only a cpu and cpu fan installed? meaning no ram, no gpu?
 


Um no i haven't tried that but it only act this way sometimes, it doesn't happen all the time. Like i'm using my computer right now and everything is working perfectly fine and has been for the past two days. Ill try that though
 


my idle temp on cpu is usually around 25-28c. And ill check on that, but it's underclocked to 1333mhz for some reason when it's suppose to be at 2400hmz so it probably is on XMP. Thanks for the reply guys.
P.S i should also note when my computer freezes, my mouse turns off, my keyboard turns off, and so does my headset. So it must be a mobo/bios problem or something
 


I enable XMP, same problem happens. I've notice that my bios setting never saves. And it never goes straight into window, it always loads up Bios up. I've set boot priorities to my hard rive, I don't know why it loads up bios first, then from there i have to boot it through the hardrive. What is going on
