Basically - once my PC is 'ON' it stays on for hours or even days with no trouble. When I shut it down (none of that hibernate stuff - 100% off)...it won't turn back on when I hit the 'power' button.
It seems like the way to fix this is to give the computer a good smack...after a few hits, the power button will once again turn on the PC.
I've had this problem for a while now and it seems to be getting worse. I've replaced cases and the problem remains - so I'm fairly confident it's not a bad power-on button.
I want to fix this - but I don't know what is really going on. My guess is that it is a bad power supply. I've completely taken apart and reassembled my computer - it didn't help (so I don't think it is simply a loose cable somewhere).
Does this sound like a PS issue? Is it possible my motherboard is at fault? Is there any way for me to test these things without purchasing new hardware?
