I own a dell that worked quite well and now wont get past the "starting up" screen. it wont even go say that its working, not one line will go across the screen. it wont boot/work any disk; cd or floppy. i would like to run my xp but it wont read anything. im trying to figure out the step in which place the error is occuring. i would like to run any sort of operating system but they cant.
