I have an old iwill xp333, and the built in sound card doesnt work, and it starting to shut off on me. i went out and bought a new asus a7n8x. i also bought windows xp, to replace windows 2000. now when i boot up, the old win2000 wont start up, but when i try to install winxp from the cd, it locks up during install. i also tried installing win200 over again but a screen comes up with errors. i have tried 2 diffrent hardrives and i still cant do a format or install. can anyone give me some ideas i can try next?
