New PC build power issue

Barrythe chopper

Hey guys I built a PC with a friend of mine yesterday we bought the parts from hardwareversand.de, all was going well until I turned it off and it wouldn't turn back on again, The first time it happened I got it going again we just plugged the motherboard out and in again and jiggled the cords and it worked fine, Last night it was working fine too until I turned it off to install a some drivers then it wouldn't turn on, I noticed as I was putting it back on the shelf the PSU power light was coming on so I jiggled the cord and it came back to life and was fine but now again its dead after being turned off any ideas on what is up? the build is

You could have got a better graphics card.

Are you sure the cable doesn't keep getting moved? Is there something hitting off of the cable?

from what i see it seems ok and I couldn't afford a better one just yet,

BloodBath

Fair enough but you could have got a weaker cpu and a stronger gpu if the rig was for gaming. I guess you can still upgrade the card in future.

Any luck with the power?

That's what I plan to do and it is my first PC and im pretty happy with it so far :-) No still no luck this time I cant seem to get any thing out of it,

I just got it looked at the problem seems to be the cable from the switch to the mobo plug

try reseating the power and reset switches.. They`d be those tiny fiddly little fookers that go from the case to the mobo... same thing happened to me a while back and that sorted it.

hopefully this will be all that's wrong now YAY! for first time gaming pc build!!!
