First of all, I would like to say thanks for the reply and cleaning instructions. I think I mentioned somewhere that I take care of all software maintanence such as adware (yeah, I know about the FREE scan crap), deleting temp files, email, disk cleanup...etc. I am not new to computer software, just hardware. I will see to cleaning my computer. Once again, my computer runs fine, just not as fine as it started out to be. I'm telling you, this really isn't even a problem, just a minor annoyance that comes up maybe once a month ranging from a bad shutdown (I take care of that with shutdown supplements) to an unrecoverable stand-by.
If the computer's insides are close off, how does so much dust get in?
