Im no expert but ive had very similar problems with a PC before that were down to it overheating.
Make sure you take the case off every now and then and give it a good clean, a dusty PC can overheat very easily. Also make sure there is plenty of space around the side of the PC box especially around the air vents in order to keep it ventilated to prevent overheating. Ideally you want to have about 6 inches of space in front of all the vents on the box for it to ventilate itself properly. Also make sure the cooling fans are working properly if they arent then the PC will heat up extremely quickly.

One way to tell if its a physical fault, when you turn the PC on, put it in to the BIOS.
Very easy to do, as soon as you turn the PC on, keep tapping either the 'F1','F2', 'F10' or 'delete' key. (It should say on the screen when you first turn it on, e.g. 'F10 to enter setup'). When you have put the PC in to the BIOS, leave it on this screen for a couple of hours and see if it restarts.
An over heating CPU can cause the PC to restart. You should be able to see the temperature of the CPU in the BIOS, use the arrow keys to navigate to the power screen and look for the CPU temp. It shouldn't be much over 60-70C.
If it does restart from the BIOS screen its most likely to be a physical or hardware fault. If it doesn't restart on this screen then it is likely to be a software/windows fault.

Or download Speedfan HERE The link is the blue Speedfan 4.40 in the second paragraph just below download it gives you the temperatures of CPU/PSU/and hard drives,you can also control fan speeds if necessary
Mother in law had the same problem. It turned out to be a loose connection on the fan causing the PC to overheat.
it does sound like overheating, my old laptop used to do it all the time. as the fan was on the bottom i used to have to lever one side of it up to let air circulate.
try a hoover on the fan, if it's been collecting dust it can stop it working properly.
