Just built a computer with all brand new parts for a friend, and I'm not getting any power to it. I tested the power supply on another PC and it works fine.

I quadruple checked all the connections, made sure everything is in the right spot, ensured its plugged in (lol), used different power cables, different outlets... any ideas?

 

[PurpleSky]

Check the motherboard power connections. If everything is connected well then we might be talking about a motherboard failure. Did you try a different Psu on the motherboard ?

 

[SirAdrian]

Yes I tried my working power supply in this computer, and still no power.

Any specific ways to test whether or not the motherboard being dead is the case? I really don't want to have to ship it back if it can be avoided...

 

[PurpleSky]

You can try to power it up out of the case with bare minimum. cpu and fan + ram and the videocard (if you have an onboard one use that one ) but i wouldnt think it would be any different. Sorry for the bad news.

i had a similar prob with a pc i built about a year ago, turned out to have been a dry solder joint on the back of the 20 pin connector and it wasnt makin a good circuit, only option was to replace the mobo (which they refused to do under warrenty, claiming i did it).
