    That usually means the system is overheating. make sure all your fans are working.

    You should download the free software from Everest on http://www.lavalys.com/ and run this while you are gaming. This will tell you if the system is overheating and which chip it is most likely to be.

    Sounds like your graphics processor is spreading too much heat to your cpu. A hot cpu shuts down a system. A hot psu does so also. Your mobo should run around 120F. Your cpu around 110F. Too much heat can change the value of any electrical component then they become erratic.

    If you haven't already, can you try opening your PC and blow out as much dust as possible. At the same time inspect the fans on the motherboard and graphics card fan (if there is one) to make sure they are working properly. Sometimes when they get clogged with dust, they burn out or spin too slowly even after cleaning.

    It could be that your PSU is overheating too - don't try and open it, just make sure the vents are all clear and the fan is running properly.

    That's when a PSU Tester and multimeter comes in handy.
