PC switches on and off after a few seconds Tags: Motherboards Last response: January 3, 2011 10:41 AM in Motherboards Share kylothian January 3, 2011 5:12:47 AM Howzit guys. Everytime i switch the pc on, all fans goes on, (no BIOS beep) and switches off after 5 or so seconds. I stripped all the components, leaving only the motherboard, cpu and PSU intact still does the same. I tried a different powersupply but to no success it switches on and switches off 5 seconds later. I think it might be the motherboard that faulty Any thoughts? More about : switches seconds mosox a b V Motherboard January 3, 2011 10:41:38 AM Try reseating the CPU and applying new thermal paste.
