I truned off my dell taptop the wrong way and then for some reason turned it back on. It started to beep and for about 4 minutes did not come on but continued to beep. When it finally came on it started with a white line and finmally the whole screen was white. It do not see anything on the screen because of the whilt. When I hook up an external moniutor (My TV) I get the desktop screen. Since I was able to get the screen I tried to reboot, but the same whilte screen with the lines coming first came on. Did I damaged the video card or the OS or the mothherboard? The OS is xp pro.
