I have a custom version of XP (maybe thats a problem too) that mixes XP with Vista visuals (such as that thing where u can scroll through all the windows) and it says that apparantly I have SP3 installed...
im thinking i might reinstall regular windows XP
Yeah, if you installed that Vista customization pack, from a guy named Dr Windows or some weird crap like that, with the documentation all in broken English, I know which one that is. Terrible pack, just makes me hate Windows Vista even more. You can't get rid of it, the guy built a totally broken uninstaller that does a totally horrible job of "uninstalling" (that is, breaking your system, not uninstalling). Pretty much the only way out is some major open-heart Windows-folder surgery (like I did a long time ago when I tried it), or just a reinstall/reformat.
SP3 isn't even final yet, and I don't trust it for a crap. A much better replacement during installation is RyanVM's Post-SP2 Update Pack, which contains all the MS updates since SP2 came out (a great many), and integrates them into Windows during install. SP3 is pretty much the same thing with the term "SP3" applied to it.
But I don't think that is your hard drive problem. There's a common default misconfiguration on many "enthusiast" system boards that sets the SATA controller into IDE mode, meaning it acts like a regular old IDE controller instead of running at full SATA capabilities. This mode is used for compatibility with the Windows installation, after which point you install the SATA drivers (if you can), and switch back to AHCI (Advanced Host Controller Interface) or Native SATA mode. That'll make everything so much faster and remove your lag problems... if that is, of course, what mode your controller is in. That's why I asked about the device manager thing.
No doubt you made some edits, so lemme go back and read those now.

edit: Oh yeah, your configuration is fucked, it's not only running in IDE mode, but it's also using default Windows drivers. Jesus, how do you sleep at night? I'll have to work on that tomorrow... it's 4am now and I think I might need to wake up in 5 hours.
