I've just built my new PC, and it's been going fine for the first few days. Now it has started to randomly "cut off" at times, where the speakers and the monitor will go dead, but the computer itself carries on running, but the processor seems to run at 100% because the fans on the cooler ramp up? I then have to hold the power button down to turn the machine off. I have the newest drivers for all of the hardware I have installed...Any ideas on this??
It can happen as early as the password screen, or at most, 20 minutes into use. It doesn't always happen when under intensive use either.

SPECS:
Windows 7
i5 3570k
MSI Z77 mpower
GTX 480
samsung 120gb ssd
8gb corsair vengeance
cx750 PSU

Any help would be greatly appreaciated! :)

The ram is fine, just tested it. And I have removed the 4.4 overclock I had on it. I also reinstalled the Nvidia drivers thinking that could be the problem since the computer is still active when it cuts off. But no, it is still happening :(

when it all cut off please press on your GPU into the socket maybe it isnt well fitted
(happened to me with my first rig so i just putted a piece of plastic to secure it

and may i ask , is the gtx 480 from a different manufacturer than nvidia like xfx or asus or such)

I've traced the source to be the 480. On internal graphics the system works perfectly! But I did have the card put in correctly, and i had the newest drivers installed, so it must be a faulty card :( Unless there could be something else i've missed with it?

Told ya!
try to RMA it , or just try pushing the gpu into its socket when the monitor turns off
