|I know there was a topic about this back in 2005 but it never seemed to get resolved and my problem is a little different.|
So I just inherited a free motherboard and processor from a friend who upgraded. Got all my stuff installed and works fine if I lay it flat on the floor. But when I stand it upright it turns off after a few seconds to a minute. If I try to turn it back on after this happens it will power up and shut down almost immediately. And this is a complete shutdown, no power to anything. Lay it flat again and it boots right up no problems.
I don't believe it is the power supply as two different power supplies have lead to the same problem (and they both work fine in my old case/mobo). I also thought it might have been a faulty power button (inherited his old case with motherboard and processor) as when it shuts off it seems as if I had been holding the power button in for a forced shutdown. But turning it on flat, pulling the power button lead from the mobo and turning it upright leads to the same problem.
I can't wrap my head around anything that would seem to be caused by the two different positions. I have tried swapping out video cards and ram hoping maybe it was something faulty there but I'm thinking it's something with the motherboard now. The friend insists he never had that problem and the only thing really different from his and my setup was I have an IDE hard drive and he had SATA drives.
Any ideas?! I'm not sure where to go from here or if it's anything that could be fixed by playing with connections. I have a hard time believing it would be something in the circuitry of the motherboard though just from a change in position.
Any ideas?! Anyone?

Any other info needed please ask. I really just want to get the tower under my desk and off the floor :)
