I have a Dell Inspiron 531s, running Windows 7 AMD 64 x 2, dual core 5600+ 3gb.
I will try to explain my issue as simple as possible.
If I am watching a u tube video about 1 minute into it my computer goes into turbo mode (sounds like the fans rpm's go off the charts) and sometimes the computer will lock up. Now if I switch my power mode from Balanced to Power saver that eliminates the fans from going turbo but then my computer runs slower. That's it. I have speedfan and monitor the temps and fans rpm's. Any help would be greatly appreciative. Heatsink issue..?
