Recently found a problem that baffled me..... Computer keeps turning off after a while. Top of case (PSU) is hot to touch, but cools rapidly if the case side is removed. Added an extractor fan to the back of the case and system is stable again. BUT.... The BIOS reports a CPU idle of somewhere around 57, seen it as high as 60 . Rather not think about it at load Is the PSU on the way out? If so why the hot CPU? Is the CPU on the way out? If so why the hot PSU?
