What causes a computer to slow down other than viruses / spyware? [anti virus] [spybot]
Q: A friend of my computer is running really slow lately (since 3 weeks ago), and he has done scans with Ad-Aware, Spybot and Avast! Anti-virus (all up to date). It takes approximately 2 minutes to print a page, and used to seconds.
He s take turns Win2k Pro, so it can not be a system restore.
He said that his computer has a lot of dust inside, but that would not really cause a this.
Any ideas do?
