ok so the other day i just plugged in an old 13 gig hard drive to my computer. i allready had a 40 gig hard drive running windows but i just wanted to see what was on this drive. so then when i was done looking around i turned my computer off. then when i booted back up everthing went fine booting into windows 98. but when it was done booting my computer was sooooooo slow it took like 3-4 minutes just to open my computer when i double clicked it. whats going on. when i plug the old hd back in, everything works fine.
