so i recently upgraded to windows 7 64 bit from windows Vista on my laptop. This laptop is mainly used for gaming so i was a bit surprised when i was playing a game and my computer overheated and turned off for the first time in a year of having the laptop. I checked and even games like "lord of the rings online" that pushed my GPU to about 70 degrees on vista, now pushes the gpu to 100 or more. Is there any fix for this? or is my only option to return to windows vista?
