Overheating

you can check if it is overheating simply
download this program
http://www.download.com/SpeedFan/300...ml?tag=lst-0-1

its free and it should tell you the heat of your processor and any other sensors you have(it doesnt work with some systems and dont play with the clocking part unless you know what ur doing)

this program also allows you to control the speed of your fans. Most new comps have a feature to slow the fans down after start up, so you can put them back up to 100% to keep everything cool
