OK.... so i was i was having unrelated problems with my laptop so i was in the process of restoreing it to stock by useing the default programs disks when i was finished everything was good the computer asked me about some of the display settings and i was'nt paying attention and just clicked. i cant remember exactly what i clicked but ever sincs ive had a black screen when i start my computer. it will boot up though. it comes up with the dell screen and the windows xp when i turn it on but when the main screen is supposed to appear the screen goes black but the computer remains on. how do i solve this problem if i cant get anywhere on my computer due to the black screen! the the screen still lights up but with a black screen. i already tried the fn key with the up arrow.
