(please see profile for pc details) Hi everyone, I built (well, tried to) my first pc yesterday. Plugged every thing in, pressed the power button and... all the fans did about a half turn then nothing. I took the mobo out of the case and tried again but same problem. I've tried a different psu- same again. Tested the psu, that's working fine. This is the forst amd 64 system I've messed about with. I'm hoping there's something glaringly obvious that I've missed as the power is obviously fine and getting through the mobo ok. I did try resetting the jumper switch but this didn't seem to have any effect. I've been ever so careful with handling all the componants to prevent static charges too. Don't know if it helps you to know this. But after that quarter turn on the fans nothing else happens if I press the power button again, but if I remove the power cable and reinsert it, it will do the same again. Also, I had the usb wires plugged into the mobo and after a while they seem to get hot- short circuit somewhere? Thanks for any help- don't really want to admit defeat and send stuff back without thoroughly checking everything.
