    The screen on my computer flickers white and blue horizontal lines when it tries to come out of sleep mode. It can take anywhere from a minute or two to several minutes to return to normal. Neither rebooting nor removing the battery have resolved this problem. :confused:

    Reseat the graphics card and clean the connectors from monitor to graphics card and see if that helps. If not then it is either the graphics card or the monitor. If your MB comes with an onboard video card then switch it to that and see if the problem persists. If it does then its the monitor. If not, Its the video card. If it does not have an on-board video card or you do not have another video card to test this, then try a different monitor.

    Sounds like there's an issue with your video card. Did you try a system restore?

    Also Check Device Manager:
    1. Right-click My Computer
    2. Select Manage
    3. Select Device Manager in left pane
    4. Expand [+] Display adapters in right pane
    Does your video card have a yellow or red icon (indicating a problem)? If so you might have to reinstall and update your video drivers.
    And please tell me which the name of the video card installed.

    Could be video card or monitor hence why I asked him/her to run the diagnostics.

    Yes you're correct about making sure it could be the monitor and running a diagnostics! While I was typing my post you hadn't posted yet. I took to long (at work lol) Sorry about that.

    Try updating your graphics driver. Drivers that are not WHQL are not guaranteed to work with sleep or hibernation. They need to be able to reinitialize after waking up.

    Does the same happen with hibernation?
