PC won't turn on but not a power supply problem? Please Help....
I'm completely stumped by this one - I have 2 old pentium III 1ghz
computers and I wanted to swap the power supplies over as one was quieter than the other. The only difference between the 2 power supplies was one was the new one had a total output of 135w and the old one was 125w. I swapped them over and it turned on and booted up for about 25 seconds but then the screen went blank, the fan on the CPU stopped spinning and the only activity was a green LED on the motherboard. I turned the PC off and then it wouldn't turn on at all. I checked the new power supply and the fan doesn't spin when I put the power cable in, thus indicating I may have managed to kill it. I have now put the old working Power supply back in and the fan spins when power is attached but the pc won't turn on. Is there a fuse on the motherboard I have may have blown? or have I blown the whole motherboard? Any suggestions on what I should do? Thanks in advance Andi |
