My system is slow, but not for normal reasons
I like to think I know a thing or two about keeping my computer running well, but this problem is no normal malady I don't think.
Lately my laptop on windows XP (SP1) has been extremely inefficient. Programs will freeze every time they are started (i.e. dell musicmatch jukebox, internet explorer) and other functions often will not initialize when I click on them (i.e. my computer, control panel, disk cleanup utility, and sometimes mcafee virusscan). A few programs that work consistently are AIM, mozilla Firefox, and spy sweeper as well as Teamspeak, version 2, which is actually a background process I think.
Sometimes however, after closing one program like AIM, or right before I shut down, "my computer" will initialize, even though I clicked on it long ago.
I have scanned my computer multiple times with spybot, adaware SE, spy sweeper trial version, and (when it will open) mcafee viruscan. I have defragmented the hard drive and have tried to use disc cleanup, though it will not work. No malicious software is detected.
I can include the log file I saved from a recent Hijack This scan, if it will be of use. Please help!
