Okay lets do this

I need to figure out whats going on with this desktop, because my brother is blaming me for everything wrong with it lol.
"CAUSE YOU DOWNLOAD ALL THE MUSIC"
I've never used this computer to download music.


The Problem: When playing games (offline and online) there will be periods of lag that last around 1 minute. There doesn't seem to be any trigger, or any particular pattern as to when it happens. At the beginning it seemed to only be an online problem, but now its both online and offline. My drivers are up to date, I'm running AVG and its found nothing, Spybot found some malware but removed it.

Specs:

AMD Phenom(tm) 8450 Triple-Core Processor
4gb memory/RAM
Microsoft Windows Vista Home Premium Edition Service Pack 1 (build 6001), 64-bit
GeForce 9100
Realtek High Definition Audio

It's an HP pavilion p6152f pc

notes: untrustworthy sites have more than likely been visited. Computer not maintained all that well. In fact when I checked on it today it was covered in dust. B | and the bugger blames ME. pff



Any help would be much appreciated. I would like to avoid sending it in to the best buy geeksquad because they're about as helpful as 'apple geniuses'.
