Try starting the computer in safe mode & see if the problem occures.
To start in safe mode turn it on & as soon as the logo, or post, screen diaappears start tapping F8
you should get a screen with stsrtup options
use the arrow key[s] to hilite Safe Mode & press enter
Finish starting in safe mode.
If the computer runs with no problem you have a driver or software issue.
If it restarts it is a hardware issue.
The 3 most common causes of a unit just restarting is the CPU overheating, video problem, memory problem.
A bad power supply can cause it also.
