hey guys.. so i have a pretty weird problem. i am running a mini itx mobo m1000 with an itps. My computer will randomly turn off while its operating, and it wont turn back on again. The standby usb power doesnt stay on either. meaning, normally i have a usb hub plugged into the computer, and whenever there is power to the computer the LED on the hub lights up, even if the computer is off . I checked the output on the itps, which feeds into the computer, and there is power there. But then randomly, when i am driving around, randomly the light on my usb hub will light up, signalling that the computer has power. And then i can push the power switch and the computer will boot up. So what i want to know is: is this a motherboard issue, or something else? is it possible that my harddrive has been corrupted somehow, and when it gets stuck or hits a bad sector, it crashes the entire computer? but that wouldnt explain why i lose power everywhere. Please help. Thanks in advance guys.
