My son informed me the other night that his PC completely crashed and would not reboot at all due to a Critical Process Died error message. He brought it out into our little "work area" for me to take a look at it. With it on its side and the side cover off, I checked to see if the CPU cooling fan was working. It spun completely freely..no resistance whatsoever. But, as I had touched the fan I noticed one of the lock-down pins securing the fan to his Intel processor "wiggled". Checking those pins, three of them were loose. This PC has run well for about two years now without any serious issue. Once I secured those pins, the PC came right up like nothing had ever happened to it. MY question: Is this actually an issue with Intel lock-down pins working their way loose? I've never encountered it before now. And, yes, I do know that they were totally secured when the PC was put together....I built it myself.
