If you were getting 80º the heatsink was probably not seated correctly.
If you do a repair install, you will not lose your files.
Only Windows is affected.
If you changed chipset, you should do a fresh install. Backup your files before you do this.
Yes the heatsink was not seated correctly, i bgroke one of the four pins, and i think i didn't get another one of the down properly looking back, but i wanted to get rid of that stock unity anyway, the one i got was 20 pounds and it looks really cool, keeping me at around 20 degress is that good bad?
I have anew priblem now, when ever i plug in the sound card, my gt wont boot up the screen on start up...
