Help me out! System crashing randomly.

My 3 month old computer has been crashing out of nowhere. For a moment, it just runs, then BAM. The whole system just shuts down on its own.

There's also a BSOD once in a while.

I think these might be the reasons why my system's crashing:

-PSU not powerful enough? I think this could be causing my system to shut down randomly when its being stressed. Maybe the cables are not properly attached to the mainboard.

-Cables connected to the hard drive could be loose, causing the BSOD?

This is my system's specs:

-Intel i5-3330
-8 GB RAM
-128 GB ADATA SSD + 500GB WD Caviar Blue
-AMD HD 7850
-MSI Z68 Motherboard

I'm using a 500W PSU from Xigmatek.

Any help is much appreciated. Thanks!

    The model number is XCP-A500. The entire system runs constantly at about 46 degrees C.
  3. Your problem is your psu. Its not powerful enough to run your 7850 gpu

    Radeon HD 7850 - 21A and a 500W psu minimum

    Your psu - 20A and 500w

    You need a psu with a higher amp on a single rail.
