A while ago my HP Media Center PC (P5LP-LE motherboard) had a power supply problem. The computer was on, but there was no display on the monitor. Then when I tried to reboot, nothing would turn on. There was some smokey smell, but it happened all of a sudden; I was not there when this happened. So I am thinking that the PSU just shorted out - no idea why, since the computer was not working hard and it had run for over a year just fine. Mind you, it was an $80 700W PSU. Maybe that had something to do with it.
Anyway, today I've been trying to figure out what went wrong. I have since put in a spare power supply, just to test if the old one is broken. With the new PSU the computer turns on but shows no video. Again, the motherboard is a P5LP-LE. The beep code is: 1 short followed by 1 long. What does this beep code mean? I have been trying to find out without success so far. Right now the nVidia 250 GTS video card is not in the tower; I am attempting to use the onboard VGA.
Since the computer does turn on with the new PSU and did not with the old one, I'm suspecting the motherboard is fine.
Any help would be greatly appreciated.
