Hello I recently purchased a pc I5-4670K - msi gtx 770/oc - 8gb ram - 500W - 120GB ssd & 500GB HDD and I got it thursday worked fine for a day but then while I was on a game (not playing it) suddenly I could hear a weird noise and the monitor turns off (monitor going to sleep) I turned off my pc and tried turn it on after couple of minutes, the monitor showed no signals and my pc shuts down after 5 sec. I waited a whole day to see if the problem solved. Now the pc won't shut down but the monitor shows no signal I changed and plug the monitor to the motherboard and it worked but after a couple of minutes the monitor goes black again now I've trying 2 different monitors and still won't work. PLEASE someone could help me and tell me how can I solve this.

-sorry, im not that good in english :)

Does your PSU have 12v 42amp on a single rail? does it have an 80 plus certification?

See that is the problem right there, you need 12v 42A on a single rail, and your PSU only has 38A, try the card with a better PSU, if the card doesn't work you might have caused a shortage on the GPU, and you might have to return it. Never invest in a cheap PSU or you are asking for trouble.
