First Build Problems?

[reckliss]

Hey,

If some of you remember a few weeks back I posted a topic on building a gaming computer with a budget of $1,250 well now I have all the parts everything is connected. I have a few problems my sound just doesnt work at all after installing drivers. And now after a while (5-10mins on first boot up within like 12 hours) my computer will just restart but nothing will appear on the screen.(That is after the beep happens from motherboard) After turning it off if you try to turn it on within 5 mins nothing will show up on screen. Does anyone have any ideas?

(All temps are at low to medium work these were the temps right before it restarts used everest)
Temps:
CPU: 39C
GPU: 40C
HD: 36C

Specs are in Sig

Hmm... Well does your motherboard have built-in sound? If not, you will have to buy a sound card, if not, double check all the wire conections. Hope this helps.
