sounds like you removed hardware and did'nt re-install properly, plz re-check all cable connections inside pc all the them!! and make sure all cards are properly seated,winXP will install a basic driver so you have video but if the cables are not connected proper you will get nothing, when you do a re-install of win xp your first move is too go into your BIOS and set the bootup tab too boot from cd first,then do a new install(not upgrade) and format the drive using the option in winXP setup upon finishing install XP will reboot, at this point you have too go back into the BIOS and set the bootup too boot from hardrive first or it'll keep booting from cd and you'll get know where, I just did this last weekend on my friends pc and it was driving me nutz as i forgot too change the bootfirst back too hardrive grrrrr lol.. so recheck all connections and get into BIOS then let us know how your progress is going ..ok? rgr that:thumbsup:
