Random Restarts.

my computer plays for about 30 minutes then restarts on its own, after the first time its about every 2-5 minutes for the restart. I felt everything and its cold so I dont think it's overheating. plz if you can msg me on AIM Karter4130, or selfmethod. thank you.

 

Bad or dirty RAM Modules can cause random reboots as can a hot processor. Make sure your fan on the processor is working and the heatsink is clean also make sure your powersupply fan is working along with any additional case fans. If all of that is good then try removing the RAM (make sure the machine is off and unpluged and that you are properly grounded) and gently clean the contacts with a pink pencil eraser and reinstall them and see if it helps.
