Was watching a TV show yesterday, went to get some snacks, came back, my system was on, tv got no signal. Hard Rebooted system a few times, nothing. turned off my ups, back on and tried again, this time, fans spin, but the power led does not turn on which is rather odd. removd the ram i the hopes of hearing beeping, nothing. is it the cpu or mobo?
How could we possibly know? Similar symptoms. Try either a spare CPU or mobo(or take it to shop to test)
