Ok I have a really odd one for you guys. I've noticed that whenever I plug in my printer, my external HD, or even my iPod, my CPU doesn't go up, but my fan starts whirrring and purring like crazy. This doesnt happen with all USB devices, such as my mouse or my thumb drive, but with these others it does.

This still exists even after reformatting my computer and checking for viruses and stuff.

My comp is:

Sony Vaio PCG-K25
2.8 GHz P4
1 GB RAM (128 MB devoted to IGP vid card).
SP2 on XP pro
~2 years old

I don't know if I have some overheating problem or if there's dust in my fans or what, and it's getting really annoying. Sometimes I get a little bit lagged when I do my work, but the CPU isnt being used up at all. HELP!

LP

happens to my dell seemingly the PSU speeds up its fan depending on how much power is being drawn (it assumes more power drawn means the system is working hard therefore it tries to cool it)
