My PC keeps rebooting when I do video encoding, watch movies and etc. I am using a P4 3.2 800FSB CPU and I have recently installed the Thermal Take Silent Tower CPU cooler. I am using two 80mm 21db Fans in the front and back of the case and Corsair TWINX DDR3200 dual channel memory and my CPU temp is around 40 - 50. Can someone please give me some advice on how I can stop the PC from rebooting and why it keeps rebooting during encoding and using certain applications/softwares. Can someone also tell me what the CPU tempreture should be normally for a 3.2 and should the TT Silent Tower CPU cooler make A difference on the tempreture and performance.
