    Hi,

    I have been experiencing some flashing on my laptop screen. It's the L502x XPS 15

    I have attached 3 videos illustrating the problem:

    https://www.youtube.com/watch?v=7jw3S6k1LR8
    https://www.youtube.com/watch?v=u3TG7IJkyIU

    The examples are quite mild, sometime the flashing lasts for several seconds.

    If it's bad enough, the display driver will crash.

    And while trying to write this post, I got BSOD'd:

    Here is my system information:

    I also have another windows 7 OS installed on another hardrive in my laptop, which experienced the same flashing problem.

    I would like some guidance on how to go about fixing this problem.

    Many thanks for reading and your help!

    EDIT: I have tried updating my display driver in Device Manager and it says its up-to-date.

    Did you install new applications or made any changes in your computer settings prior to the problem?

    If yes, then just simply uninstall the new applications you installed or revert all the setting changes that you made.

    This should resolve your problem or you may use System Restore to restore your computer to an earlier date before the problem started happening.

    Hope this helps. :)

    No new changes. Again, I wanna mention the OS on the other hardrive is also experiencing the same flashing.

    Thanks harp, I ran the update and installed all the drivers but none of them were display drivers and my problem still isn't resolved.

    I had a look at your first link, I don't know what I'm supposed to do with that. Any help?

    The first link was just to show what had caused the blue screen.
    If it is happening when using different hard drives - then it is likely to be the laptops hardware, motherboard, graphics card, etc.

    The following will test the graphics card - I have never needed to use the program so, read all information before using the test.

    I ran the program. I did the stress test for about a hour but nothing happened.

    I also did the benchmark test and this was the result:

    For the testing though, it kept testing the nvidia graphics card but I think the display driver that crashes is related to the integrated graphics card.

    So i don't know what to do :/

    I do not know how to interpret the FurMark test.
    I will ask one of the Moderators to move your thread to the Hardware Forum and one of the experts will help you there.

    Hi,

    First thing I would like to try is connecting to an external monitor of somekind if at all possible. If you can do that can you let us know if the problem is also present on the external monitor.

    The flickering itself actually looks a bit like a failing backlight / inverter board, however I wouldn't necessarily expect to get display driver crashes and resets as a result of that hardware failing (that doesn't mean it can't occur though). If you move the LCD screen (as if opening or closing) does the flickering occur any more?

    Are you using the laptop manufacturers drivers for the Intel graphics card or updated them direct from Intel?

    Tanis, thanks for your help.

    I don't have access to an external monitor currently. However, I will do on the 14th/15th March. I can try to confirm if the problem persists then.

    Moving the laptop screen doesn't affect the frequency of the flickering.

    I don't know which type of drivers I am using. Any way I can confirm?
