My wife is currently on her 3rd motherboard in a bit over a year and a half. I recently replaced her fried 2nd motherboard just over a month ago and everything was working fine until tonight. At first her front 2 USB ports wouldn't recognize any devices ( the back ports worked fine ), then the computer just blinked out completely. If I turn off the power switch in the back and then turn it on, I can power up the PC for a split second before it crashes again. I thought maybe the PSU was the culprit ( much as I thought the same thing when her last motherboard died ), but after trying it with my PSU tester, everything spun right up so I'm ruiling out the PSU...again. My best guess is there's something about her case which is causing these mobos to short out, we've had 3 different brand mobos ( Epoch, Giga-Byte and Asus ) and all have died. I can't believe it's just bad luck...any ideas or suggestions would be greatly appreciated.
