This is the first time I am seeing this problem with my computer. Actually I am using the ASUS P6T motherboard on my computer in which I have installed a compatible processor. Today I have noticed that all of sudden CPU temp goes above 80 C when the system is Upright and working heavily. When it become idle, the temps drops to mid-40C. if I start something again, the temps goes up and drops down when it is idle. Everything is happening in a fraction of minute. I donít know why the heck it is acting like that.
