    So I have upgraded my GPU from a Radeon HD 6770 to a AMD Radeon HD 7770 GHZ Sapphire edition, and I am getting only a black screen unless I boot in safe mode, which is annoying. Please could anyone help.

    Did you uninstall everything related to the previous device before installing the new one?
    In safe mode, go to Programs and Featuress and do that. Also uninstall anything related to the new device, if there is anything. Then go to Device manager and remove any and all Display adapters. Answer "Yes" if asked to remove the driver(s). DO not reboot until all Display adapters have been removed.
    Reboot and you should be able to install the latest drivers from the manufacturers website.

    How to properly install a new video card;
    1 Old card still installed, go to the respective support site ie nvidia or amd. Download the latest driver
    2 Old card still installed, uninstall ALL software based on the old card ie driver, any monitoring software, any suite, etc. When it asks to restart, just tell it later
    3 Shutdown and pull the old card. Install the new card and make any pw connections as necessary
    4 Pw ON and install the driver you downloaded in step #1
    5 Reboot when prompted


    It would REALLY help if you post all of your exact system specs; ie exact motherboard, exact pw supply, etc, etc. Do not post "500W pw supply" Post the exact brand and model# Do that for all of your parts.
