    Hello. I am new here and hoping that somebody might help me. I have a Toshiba Satellite L505 laptop. I have read the topics about vertical lines on laptop screens here but my case is different. I suddenly got these vertical lines all over my screen, about 1 pixel thick and 7 to 8 pixels apart and that when it appears, the system crashes and freezed. I tried to reboot but when the desktop icons start to appear then the red vertical lines also appear and that the system freezes again. When in safe mode, it works fine. So i tried to re-install the windows 7 32bit system from my package. After installation it works fine. But when I restarted my laptop again it showed red vertical lines and system crashed. Everytime this happens I have to re-install my windows 7 again and again just to use my laptop. For now, I don't shutdown my laptop because i know that when I will start it up i will have the same problem again and will have to re-install. I don't think that this relates to loosed connections or overheating because I never shutdown my laptop for a week now. I also tried to open my laptop to inspect the graphic card (ATI Radeon) but I cannot find it, perhaps it is integrated to the motherboard? I noticed that something triggers this vertical lines to appear like: (1) running MS DOS programs; (2) hibernating, idling and dimming to save power; (3) restarting; and (4) when administrator permission pop-up appears. Now I am avoiding these actions to prevent system freeze and having those vertical lines. I am really hoping that somebody can help me here. Thanks a lot.

    Check you on memory or run toshiba diagnostics tool... I think is when you go to recovery mode ... there has a option for hardware testing

    You might have slightly pulled the cable that connects the lcd to the graphics card or elsewhere around it. Try reseeding everything you can around the screen including the button bar with the power button in it. If this doesn't work try opening it up and pull all the components and put it back together.
