New build keeps cutting out randomly

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! :)

  1. First, I'd test your RAM, one stick at a time.
  2. Test your O.C. stability if you are O.C. -ing
  3. 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 :(
  4. Hmmm, a 4.4 OC on a MSI board? Hmmm, pardon the doomsaying, but you may have a bad board. The only problem with replacing it with Asus or Gigabyte (or even ASRock) is that you might need a new Windows license.
  5. A bad board? but the OC I had on it was stable, before this cutting off started happening. And like I said, I removed it and it is still happening..
  6. i would like to tell you , check your cpu's heat at the moment it cuts off ... and then buy yourself a better case fan / cpu fan
  7. Cpu heat is Ok. Im using a silver arrow extreme , and there hasnt been a problem with temps yet. Its at 45 degrees when it has cut off.

    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)
  9. Thermal cycling could well have loosened something. With the system shut down and PSU turned off (so +5VSB is off too), remove and reseat your graphics card, RAM, and drive cables.
  10. 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
