    I had this problem a couple of years ago. Turned out to be a faulty stick of ram. If you have more than 1 stick take all out bar 1 and try that, then then swap it around.
    It drove me scatty for weeks taking different components out etc. Tried different PSU's Graphic cards etc and it was the ram.
    I'd start with that first m8 it's probably the quickest and easiest to eliminate.

    THE TRUTH
    The Hillsborough Independent Panel. 12/09/12

    Today's report is black and white.The Liverpool fans were not the cause of the disaster.
    The panel has quite simply found 'no evidence' in support of allegations of 'exceptional levels of drunkenness, ticketlessness or violence among Liverpool fans' and 'no evidence that fans had conspired to arrive late at the stadium' and 'no evidence that they stole from the dead and dying'.

      You say after 20 mins, after that can you reboot it straight after, if yes doubt its over heating.
      Dont suppose you get a BSOD (blue screen of death, a blue flash before it happens).
      Does the event log show anything?

          power it up and go into the bios.
          Leave for 20/30 mins see if its shutting off then.
          Also check where the cpu temp and the shut off threshold are set to. This should give you a good idea if its overheating.
          You could also pull the side off the case so when it shuts down feel the heat sink and see how 'hot' it is.

              sounds like overheating and the mobo is cutting the power.

              open the side of the case and get rid of any dust you can see. switch it on with the side off and make sure the cpu fan kicks in if it does,great,shouldn't really over heat the cpu.

              next remove 1 stick of ram and re start,if it cuts out then try it with just the other stick in.

              your basically going to have to remove each bit of hardware and test with a known working one.
              eventually you'll either eliminate a hardware fault,then it must be software related.

              Start up the p.c and go in to Bios settings, (normally press f8) when booting.

              Make sure that the cpu isn't overclocked as this can also cause a cut out.

              Let me know how you get on.

              Good Luck

                      no,don't bother mate, get an artic pro,and some new thermal paste.
                      You can pick the pro up for around a tenner and it's the best
                      cooler on the market (for the coin).

                      This baby will keep any cpu cooler than a polar bears arse

                              Just make sure everything is clean and free of dust once reseated with enough paste, it should be fine
