Dude, go to www.windowsupdate.com. Get the latest update NVida driver for your card, (if they have even written one). I hate to tell you this, but XP is FULL of holes. You'd be better off installing swiss cheese on your HD. :) Don't get me wrong, I'm not dogging you at all, I'm doggin Microshit for putting out the lamest operating system yet. I thought ME had it won, but after seeing XP, I'll just stick to Win2k Pro. They put that program out half assed, and expected the public to pay full price for alpha software. No wonder the Government stepped in and Spanked Billy Gates for putting that program out. Ok, I've vented enough. :)
Anyway, check www.windowsupdate.com for latest device drivers. Oh, and BTW, wait until you see the nice little "Virus Protection" plan Bill has waiting for you :) Sometimes, more isn't better :)
Also get your security updates, (I'm sure you'll see what I mean when you get to that screen) & Directx8.1.
