Slow Bootup - Win XP - Agp440.sys hanging

[urbestfreind]

Well, on my desktop computer, I've been having some problems. First I put in some new parts (graphics card, ram chip, internet connecter...thing...and I got a new keyboard). As far as I know, everything was installed (like all the discs that came with said items). Then I got hit with a rootkit from hell, which I believe I have manage to eradicate entirely.

 

 

 

Now I'm left with one major problem - Slow startup time. The computer always did take a bit to boot, but never this long. It is taking me about 20-30 minutes to get to my desktop. After everything starts up, programs open up fine, and I don't really see any more lag, aside from what I normally get due to windows being a suckish OS.

 

 

 

I tried a bootup in Safe Mode today, and the file that it hangs on is Agp440.sys. From what (little) research I did, it seems to be like the computer trying to find parts on the motherboard that aren't there.

 

 

 

I really need help fixing this problem, because I want to get back on my desktop and start using it again (I switch to my laptop after that virus raped my computer). The solutions I've seen require the XP install disc...Well, this desktop is a hand-me-down from my grandfather (with upgraded parts), and I guess he didn't get the disc (you know, one of those premade systems from Circuit City that has everything installed already)...So I need to get a fix without the disc if possible.

 

 

 

Also, while I'm talking about the XP disc, can you use the same disc on multiple machines? Like, I found a program that can get me my product key, so can I use like my dad's XP disc (provided he hasn't lost it), and use the desktop's product key for a clean install?

 

 

 

If you need more information, or if something wasn't clear, just post or pm me and I'll try to get it taken care of quickly.

First off, yes you can use a different CD. Just make sure it matches the OS version you currently have installed or it will reject your key. So if you use XP Pro, any XP Pro CD will work.

 

 

 

I would suggest trying a repair installation from the windows disc. This will replace all the system files while leaving your programs, registry and personal files intact (back up important stuff anyway just to be safe). Doing that will make sure that all the system files that may have been infected by the rootkit have been fixed and are working as intended. This forum post (via geektogo.com) is a nice guide of performing the repair install.
