Success! Determination paid off. I was focusing in the wrong direction and got tunnel vision thinking the problem was my hard drive racing and using too much virtual memory, etc. Nope, it's my GeForce video card fan. Come to find out, it's integrated, so not a vid card?
So I start Googling for others with my unit and problem. Some fixed it with updating drivers for windows7, but that didn't work for me. Others added another fan, and this was my next move.
So I decide to look at my fan and heatsink in hand. First thing I notice on the heatsink is it looks pretty big and has 3 copper tubes running through it. So I'm guessing this must be a liquid cooled heatsink? Then looking at it more, it has a THICK dust in the fin, so I take off the fan from the heatsink and it is packed full! I'd say 80% obstructed.
So I blew it out with high pressure, clean the fan, got it back together and THAT DID IT! I put it through the worst test. Watching an embedded youtube vid, opened my MySpace page and opened a few forum threads and posted. The fan has not raced once since. I actually thought maybe I didn't hook it back up right because I can not hear it. So I put my ear to the vent and it is running. Just slow and REALLY quiet.
