Yeah, avoid NORTONS like the plague! Also, scan your system with a good 'Spyware' Prog. Like 'SpySweeper'.You'd be amazed at just how slow your system can become if it's clogged with spyware! Also, If you want to use 2 gig Ram with your Athlon you'll need a Motherboard that can take it, I know when I had mine built about a year ago I had a bit of a game finding one.
