Input Issues on Dell Inspiron 8200

[PacoL250]

Well, I've done all I could in terms of using spyware and adware checkers (I've used SpyBot, Ad-Aware, and Spy Sweeper), and I've done virus scanning with the latest definitions, etc. The only thing I can now think of, in terms of software issues, is a possible registry issue. Could there be something wrong with the registry? I haven't used a registry cleaner, etc. yet, but I want somebody else to take a look at the Hijack This log I've posted above before I continue on.

I'm also wondering if it's a hardware issue all of a sudden. I'm thinking faulty RAM or a ready-to-die HDD. Neither of those should be the case since this laptop worked like clockwork before. I'd be pissed if that's the case; I'm now been out of warranty for only a month and a half, and I expect this laptop to last longer than one freakin' year.

Then again, could it be an issue with the PC cards I have in the comp? I have a Belkin USB 2.0 card and Linksys Wireless G card in both slots, respectively. They seem to be configured properly, so I'm not sure if they could be the issue...

I hate stupid problems...

EDIT: I didn't reinstall the Linksys software for the wireless card, but I don't think I really have to, since one, it works fine without it, and two, Windows Update just found an updated driver for me for the card; the newer driver, strangely, doesn't appear on Linksys' website...weird but eh, who knows?
