Probably overheating / bad power supply.
please provide us with your power supply make & model, and with your processor and graphics card temps (could be done with a monitoring software such as HWMonitor).

It depends on the type of reboot. If it's a black screen reboot then your culprit is the power supply. If it's a blue screen then your looking at something else.

There is also a option to turn off Automatic Restart for BSOD this will give you more of a idea of what is going and if you are indeed getting a BSOD.
To do this right click on My Computer and then left click on Properties> Then Click on Advanced Settings it is on the Left Side of the Screen> From there click on the Advanced tab and at the bottom of that tab will be System Startup And Recovery Click on Settings> From There uncheck the option Automatically Restart. That way if your PC still just restart then you will know it is not a BSOD and can go from there to trouble shoot the problem more.

Automatically Restart is the default option for Windows 7.
