So while I was at work my wife called and said the computer will not turn on. She says that our daughter plugged a usb cable into it in order to charge a PS3 remote. The computer was working at this time. She removed the remote later and used it. Upon trying to use the computer later it would not boot at all. When you press the power button nothing happens. No fans spin, no lights come on... nothing.


I removed and tested the power supply via the safety pin method and it is working. I put a brand new power supply in any ways which was also tested. I next replaced the power switch button (not the full cable) and it still does not come on. I noticed after this that my motherboard has an on/off power button and reset built onto the board. Upon pressing this button nothing happens. I built this PC myself less than three years ago and have not had any hardware problems till  his.


Do you think my motherboard has suddenly failed? Do I need to replace it? I don't think it is a grounding issue as the computer has sat in the same spot and worked since I've had it till now.


Motherboard is an ASRock P67 Extreme4 Gen3

Closely examine the USB ports to look for damage. If possible, isolate them from the MB. If a USB plug was forced in or broken off then a short may have happened.


Here is useful guide also... http://www.duxcw.com/faq/mb/deadmb.htm .
