lol no your comp shudnt be ready for scrapping just yet, although you do need to get hold of another moniter to have a look and see if its that or not, have you asked your friends? if the green line still occurs on another moniter, then you need to try another graphics card. although if doing this urself be very careful because of the static in ur body can fry pc components, better to ask a pc friendly mate to help you out. just out of interest is the line there on the screen where windows xp is loading up? or just once ur logged on?
