windows 7 - No signal to monitor after uninstallation of display driver

    I was on the Sony website trying to get the latest display driver for my Sony VAIO laptop. Their instructions told me to uninstall my display driver through add/remove programs in the control panel and to reboot then visit the website and install the latest driver.

    Easier said than done, after the uninstall my laptop won't display on the monitor anymore. (My 5yr old dropped my laptop and broke the screen 2 months ago, so I've been using a monitor to display the image ever since.) Even in safe mode the monitor gets no image, although after pressing f8 repeatedly I do hear the windows start up sound.

    My model number is VPCCW21FX the video card is NVIDIA GeForce 310 M and my OS is Windows 7 Home Premium 64-bit. I just want to know how to display the image on my monitor so I can install the latest driver and finish the process but I can't see anything since it's broken.

    You should be able to boot into safe mode and reinstall your drivers. http://windows.microsoft.com/en-gb/windows/start-computer-safe-mode

    Failing this, you should still see an image at boot time - you can trigger a system restore which will get you up and working again. http://www.sevenforums.com/tutorials/668-system-recovery-options.html

    display - No signal to Monitor after uninstalling graphics drivers
  • Post

    I have a pair of ATI 5770's in crossfire and today I decided to do a clean install of my graphics drivers. So, my plan was to:

    • Uninstall drivers
    • Boot into safe mode and run driver sweeper
    • Boot back into Windows to reinstall drivers

    I didn't even get to stage 2. After uninstalling the drivers I don't seem to be able to get a signal to my monitor no matter how hard I try. The attempts I've made to solve the problem are:

    • Tried both DVI and both VGA slots since there are 2 GPU's
    • Resetting the BIOS by removing the CMOS battery for a few minutes

    No luck. To clarify, I don't even get a signal to the monitor at any point; not even during the POST process. It does POST just fine, though.

    If you're not getting any signal to your monitor even at the initial stages of boot or at the BIOS screen, you might have a hardware issue.

    At any stage, have you opened up your case (to vacuum the dust, to read the model number from the cards, etc.)? Do we have the full picture or have you actually done anything beyond what you described above?

    If you've touched any hardware, I would try trying the video cards one by one, trying your RAMs one by one (you might have fried them with static electricity from your fingers etc.), press down on cards, cables to make sure they're securely attached, etc.
