i have a dell, so, if re-install it i will lose everything? my problem is that i have an external dvd burner, it was working fine. then one day it decided to become an unknown device. i may have deleted something without realising, ive tried everything to get it to work again, uninstalling it from device manager and so on, but ive been told that the easiest way is to re-install xp. is this true? or can the drivers for everything be reset to default settings? i think it is a driver issue. i had an mp3 player whaich came with a driver cd and installed that, but when i plugged it in, it was unknown also.
