Hi guys
I turned my pc on, then left the room for an hour and came back and saw no signal on the monitor. It restarted at that time by itself and still displayed nothing. I just it down and tryed then turned it on and it would start for a sec then turn off. I unplugged everything checked it was all in, booted it and the screen showd an overclocking error in the bios (xmp is enabled for my ram only, i dont have anything else overclocked) so i go to setup and it shows my bios. I exited without saving changes then it restarted and booted to windows fine. I turned it off and went to close the close case, i went to turn it on and same story once again. Opened the case and it turned on, same error this time i pressed f2 went into bios and exit with saving changes, the pc went to reboot and it turns on for a sec then shuts down then trys again : /

I reset the cmos and it turned on fine stating it reset evrrythibg to default. 1 min in it restarted then when it got in windows it showed only 2 or 3 devices in hwmonitor then had mouse/keyboard failure so i shut down. When i booted it again it was going on for 1 sec then off and attemping again. I have an i5 4670k, msi z87ac mini itx mobo, 760gtx and 8gb corshair vrngeance low profile with xmp enabled at 1866mhz my psu is 600w pc was running fine for 1 week
