I built my new computer about a week ago and as soon as I got it working it was great until I got home yestrday from school. The darn thing wont start, the fans and leds come on for about one second then turn off and keep repeating itself. I have no clue whats going on, I tried different Power supplies. I think the mobo might have gone bad or the cpu. Any help is appreciated. Please reply as soon as possible!
Mobo = AsRock z77 extreme3
cpu = intel i7 2700k
ram = gskill sniper 8gb
case = Cooler Master elite 431
Try removing your Graphics Card, booting, shutting down, and replacing your Graphics card and booting again. Sometimes the voltage can get all effed in the Card and requires a bit of a grounding. Also, if you have another Graphics card, try that and then replace it with your new one if/when it boots.
