XP Pro and/or XP64 problems

[Drent]

Hi, I've recently started getting a really weird problem. When either Windows XP x86 boots or XP x64 boots the loading screen comes up and then it takes up to 2 minutes for windows to actually load.
I wouldn't mind except its a brand new PC with nothing installed and you cant see anything for the time that it doesn't load, originally it happened on XP x64 so i thought maybe it was GFX driver problems.

I installed XP x86 as well and the same thing happens. I don't know why because it happens on either OS even when only one is installed and the other isn't.
My PC was running fine, it's less than 3 months old and really starting to bug me. Any help would be appreciated.

The PC is an AMD 64 X2 4400+, 4GB RAM, 1 Seagate 400GB, 1 150GB Raptor, 2x XFX 7600GT XXX edition graphics cards. Currently running just XP x86 and nothing else. Thanks in advance,

:edit: The PC runs fine once XP is actually loaded. :edit:

P.S. does anyone know where I can download Service Pack 2B for XP 64 cos I can't find it anywhere on the MS site
