i went to do my regular 4 month drive cleaning, and every time i try to install xp with either cd, the installation crashes at 19 min remaining. i have a fully legal version of xp pro, but it's a burn. i also have an older corporate version and it's also a burn, but i've installed off both before with no problems. how come i'm getting problems now? could there be anything more than maybe dust on my cdrom lens or something? i've tried changing hard drives and that hasnt worked to my advantage. i've tried with both cds and it stalls around the same place. i cleaned off the cds also. i dont know what other variables there could be.
