I just acquired at Dell Dimension 8200 XP (2.0 Ghz, 256 RAM) from a friend who said it was broken. Turned it on noticed a clunking from his hard drive and the machine not booting up at all. Figured his drive was dead and I purchased a new one. First configured the drive for 98SE and then loaded 98SE. PC seemed slow so I then loaded XP on it. Took over a day to load XP. Computer now painfully slow. Takes about 15 minutes to boot up. Any ideas?
