Replacing Vista with XP: problems

I bought a Gateway MT3422 laptop. I'm trying to install XP on it instead of Vista, to try to improve performance (it's not nearly powerful enough to run Vista well).

I format the hard drive and install like normal. All the system files seem to copy over fine (except for one .dll file related to IE, which I plan to uninstall anyway), but after it restarts to do the setup portion of the install process, I get an error about "Insufficient System Resources Exist to Complete the API", and the computer reboots, continuing to do so every time in an endless loop.

I tried reformatting, this time using the full format option (rather that quick format), but it still does it.

Any ideas about what to do?

Also, /g/ is a bunch of faggots who would rather just insult me than provide an answer.

You might be missing a critical driver, perhaps the drive controller one, which you will need to install during the XP install by hitting F3 or something in one of the blue text screens.  Contact Gateway support for your model laptop and simply ask them if it's rated for XP, and if so, how does a customer load it on their own?

Let us know what you find out.  We're going to see a lot more of this sort of thing before Vista gets stable (or ungay) enough to use.
