    my monitor filled with green lines


    Hello
    I have a PC with BENQ senseeye3 led monitor .... as i was playing gta5 today and out of a sudden i started to see that my monitor is filled with colored dots and spaces and started to hear a strange noise ... so i forecfully restarted my pc and thr same thing happened as soon as windows 7 logo appeared but this time after few seconds the monitor showed "signal can not be detected" ....
    I restarted for the second time this time using safe mode .... the monitor has green lines all over ... and i can only run on safe mode ... normal mode freezes

    I checked cables ... they seem ok ..
    I reinstalled nvidiq driver ... no change at all
    My gpu is nvidia geforce 9800 gt





    So please whats wrong? Is it a hardware or software problem and where exactly?

    I dont think it would be helpful because i have logged in and shut down my oc several times after thr problem appeared ... any ways i did it ... but my system crashed upon starting ... still the only way to start the pc is with safe mode ...
    Any other help

    Thanks anyway

    Have you tried isolating this problem?

    By this I mean: have you connected to another display to check that the monitor itself hasn't gone bad?

    After verifying Mist's recommendation, try another display port of the GPU (if applicable).

    Then follow this (belongs to Mist) :)
    Graphic Card Driver Clean Installation
    1.Run the Guru3D Display Driver Removal Tool: Display Driver Uninstaller Download version 15.3.0.0 Display Driver Uninstaller Download version 15.3.0.2
    2.Download CCleaner here (CCleaner - Download) and run both the Cleaner and the Registry Cleaner to remove left-over keys.
    3.Go into C:\Program Files & C:\Program Files (x86) & C:\ProgramData and delete any leftover Nvidia files.
    4.Disable automatic driver installation: https://support.microsoft.com/en-us/kb/2500967

    6.After restart go to: Drivers - Download NVIDIA Drivers and install the latest Nvidia Package (Including the 3D Vision Drivers - Install it all).

    Thanks for the quote GokAy!

    For anyone interested the original article is here: Screen keeps going black

    My tutorial works well as long as you follow it EXACTLY as written. The steps are a way to clean-install your graphics card again to rule out a driver problem.

    Try the steps and let myself and GokAy know what happens.

    Thanks

    You need to try that GPU in another PC, if it propagated to BIOS, then I would suspect a faulty hardware. Are the fans running? You can try to feel with your fingers.

    The problem was solved ... it seems something called "AC" in my gpu has been burned ... now its replaced and the pc works just fine ...

    Many thanks again for your helpful tips ...
