No about processes. About the only thing I'm an expert on.
I had a virus on my computer about 4 years ago and did hours upon hours of research on processes and what they are. Plus I have Spy Protector which explains everything that is on my computer. Thats why this is such a mystery to me.
I don't really know about the fan problem you are having.
But I'd like to mention that my computer shuts it self off sometimes when it's too hot. It's been doing it for years and it's really no big deal.
