d/l this little application
you can over clock your pc and test your temp in your pc
this link got me out of a jam, my computer kept restarting after about one hour
I ran the application, and my 3 temps were
51 degrees C
55 degrees C
49 degrees C
So I was like damn, time for a cleaning got out my computer vacuum and pulled about 3 inches of dust....almost enuff to fit in an 8 ounce class..
but now my temps are
27 degrees C
20 degrees C
31 degrees C
