My pc froze and instantly shutdown. when i trying to turn it on its turn offs after a few seconds. after a few hours i tried to turn it on and successfully turned on and all fans were working, but cpu , gpu and ram leds were red on motherboard on manual it means error-not detected. i tried replacing psu, taking all parts one by one, resetting bios i tested almost everything that i found on internet. i thought that motherboard is dead, but next morning i just turned on pc to be sure and boom all works, looks fine windows loaded and when it got to desktop it froze again and everything again were the same all leds were red and fans were spining but no boot. AND i tried turning on AGAIN for one more time next day and its working again but just for 30-40 seconds and froze again. so i think its mobo but why its working again for short time after some time. sorry for my bad english.

my setup:
cpu i5 2500k OC
mobo p8p67 evo
gpu r9 280x
psu corsair HX750W 80+gold
RAM 8gb- 2x2gb excelram / 1x4gb crucial ballistix with LED
setup is 5 years old
