Larry, I determined it WAS the one I was looking at before, the one on the CPU heat sink. Problem is, I can't find one yet to replace it. I'll have to give my son a call later. He probably has one in his spare parts. I seen the one you're talking about in the power supply. I took the cover on the power supply off to clean it out, and it was dusty. I cleaned it with cotton swabs and air. Looks a lot better. Maybe it will help a little, won't get so hot in there??
Well it's probably psycological, but it seems to be going faster wink I don't think it could hurt, ( I hope ) Anyway, I guess I'll get my son back on it when he can. Thanks Steve..
