He'll all, yesterday I built my pc for a friend and everything seemingly was installed correctly. But today he turned on his computer from sleep mode and I wouldn't output on the go, he tried the motherboard output and that worked but with no sound. Now neither work. Any ideas? My only thought is the psu not being powerful enough.

I7 4790k
Asus Gtx 780
16gb ram
Corsair cx 600
Asus z97-k

Thank you.

Daniel.

Well i would never hook up a crap cx 600 to a nice system like that but it should be powerful enough. I would guess its a bad mobo.

Can you give us a little more background info on what you tried? You said you tried waking it from sleep mode and that that didnt work. Did you try switching it off and on again? What does it do now when you switch it on?

Try unplugging the system for about a minute, and then replugging it and starting it again. What does it do?

Well we got it all set up nicely, started up just fine after putting the parts together, installed all the latest drivers for the GPU. Played a couple of games to test it out and all was well. Surely if I had done something wrong that would become very clear long before installing the games. He's at work at the moment so I can't get hands on with it till later. I'm just looking for any help/suggestions you can give me. Thanks

UPDATE: After unplugging the power the motherboard hdmi came back to life. Now it's saying the HD audio device isn't working. Still no graphics card. Going to ge drivers for the motherboard, and reinstalling the nvidia drivers. Also hardware manager says no installed drivers for pci simple comms controller. Any ideas?
