Troubleshooting help

post #1 of 3

I'm not sure if this is the correct area, if not please let me know.

I just purchased all the parts to build 2 computers. This is the first time I have done this. The first is running fine, everything booted up, windows installed, all good.

The second is the one I'm having problems with. When I hit power, everything lights up, but then stops. It doesn't seem to keep power. I've unconnected and reconnected the PSU hookups multiple times. I've also unplugged and reconnected all of the wires for the power/reset, hdd etc. I also tried booting it up with it only connected to the mobo to see if dvd/cd burner or hard drive might be the issue, but no luck.

All of the parts are exactly the same, so I don't think it's a compatibility issue. The PSU may be borked, but at the moment I'm worried if I unhook the working comp, I might eff that one up somehow. Any ideas what could be the issue?

My take is that it could be the PSU or the motherboard, if the board is broken the computer still can't start. You could check if the PSU is running fine if you deconnect it from everything and jumpstart it - paper clip between the green and any black wire in the ATX plug. If the fans starts turning then likely the PSU is good, if you have a multimeter you could check voltages to make sure.
Removing the PSU from the other PC shouldn't pose any trouble.

It was the PSU. Took the psu from the working comp and it powered up fine. Thanks.
