PC shopping.

[Kenoi]

Well one of these days, I'm currently saving up for a whole new PC, cause this one has one too many problems. the recent one was... that anti-virus problem like I posted in that one thread, (it got resolved with norton, thanks to Jokersvirus)
and now I dont think its the software anymore, so now this computer has frequent freeze ups... nothing's wrong, I checked for spyware, etc. all that.
I think this computer's reaching its last 'mega byte' <--- I try to joke..

but anyway, I just have questions, hope some of you can help (without rude comments & stuff like that, i'm just here for help please. moderators you can help me right?) this PC is from 2005, i'm just lookin to switch.

Are Shuttle PC's good? cons? pros?

what about this computer: hp pavilion s5710f

or maybe somethin better?

also, I cannot buy a computer from Best Buy... cause they F'd us up on the return fees... always read the fine print.... they are a nasty-shady-want-your-money-so-bad type of company. (would not discuss, its a long story)

recommendations? All I'm looking for is just a home/gaming type of pc.

thanks in advance.
