i've had 98 for years and it always worked fine but the minute i tried to upgrade to xp it kept sticking on 23 minutes to go. However (now heres the good bit) it has installed enough to wipe any trace of 98 from my system and everytime i restart it tries to restart the setup program and sticks at 23mins the result.... endless looping and very dead computer any help?

p.s. it asks for a lot of dll's when installing cos it seems to find them in the wrong directories i have located or replaced all of them with ones borrowed from a mates computer will this be whats making it stick and if so how do i fix it (preferably without losing everything on the machine)
