Computer won't turn on

Louiemaster · Sep 13, 2007, 05:52 PM

Long story short, my computer wouldn't turn on anymore after a hard reset. However, if I left it plugged in, it would spontaneously turn on but wouldn't POST. All the fans would come on, along with the lights. It wouldn't respond to the power button and I've checked all the cables along with buying a new PSU.

My question is, could my motherboard have been fried by my old PSU? And is there any way to check this without buying a new one. Also, could my CPU, RAM, or Video Card have been fried too?

If you purchased a NEW PSU and it didn't resolve the problem.. it is likely your motherboard..

best way to test this is to unplug EVERYTHING... only leave the motherboard plugged in... and disconnect the cables for the hardrives or other devices from the motherboard so ONLY the motherboard/CPU/RAM are plugged in (also disconnect the external devices like keyboard/mouse/etc. but leave the Monitor plugged in)..

See what happens then,

If same thing, remove the RAM.... try again.... same thing, Try removing the CPU... see what happens... If it repeats yet again, it's definitely a dead motherboard.

yeah also try clearing your CMOS and see if it has any affect whatsoever

Yeah I've reset the CMOS like 20 times before. I'll try slowly taking everything out.
