well i got rid of the file disk error but i think i still have the delay problem it all started after i reinstalled windows i did it as an upgrade cause i didnt want to lose my music and videos..but now i seem to be having problems like the delay and certain programs have issues..when i put in the windows xp cd if i choose the other install the one besides upgrade will that erase my music or will it just do the same thing or will it just erase programs and not my files
