My father's laptop keeps coming up with a black screen after the XP logo and won't move from there. I've tried starting in safemode but that won't work either, same problem occurs. It did have a virus/trojan horse in it before but a scan revealed it and my father "dealt with it" apparently. Could this be related? I'm not much use with computer related things but I'm better then my father so I'm willing to give things a try. I don't know if we have a windows XP CD, will have a look but I don't recall it coming with one. Is there anything I can do in the meantime that might fix this? The computer is a year and a half old, Toshiba laptop.
