Random shut downs are hard to diagnose, they can be software or hardware related.

First are all your drivers up to date? This is particularly true of the graphics driver.

Is Windows 7 itself completely up to date?

If you are satisfied that the above is true then the next most likely causes are peripherals,memory and power supply.

Disconnect any permanently connected peripherals particularly USB Hard Drives if you have them and see if you still get shutdowns.

If you have multiple memory sticks in your machine then take them out one by one and run them individually to see if one of them is causing the problem.

There is no easy way to test a power unit other than by substitution.
