    One one of two displays works -- hardware issue


    Got fedup with the daily CHKDSKs on my Win10TP install so I "cleaned" the drive and reinstalled using build 9879. First thing I noticed is that, unlike previously, only one of my two displays worked!

    I check the Device Manager and the default Microsoft Basic Display driver was showing, even though I have an AMD R7 240 video card.

    I installed the AMD Catalyst drivers and upon reboot, both display worked.

    But, I started having CHKDSKs again, so I used a different drive and installed again.

    This time, both displays showed upon initial reboot. When I checked Device Manager, instead of the Basic Display driver, it showed Radeon R7 drivers!

    The only difference was the choice of which drive to use for installation.

    So, I have to presume that filesystem failures on the other drive prevented proper hardware detection and drive installation.

    So, if you run into the problem, in a multi display situation, where only one display shows, it could very well be a hardware problem with your drive.

    It stands to reason that drivers and other SW will have a problem running of a damaged drive or file system.

    That's true ... but I get forced CHKDSKs on the Win10 partition every time I reboot into Win8.1 -- and am still getting them, even though I changed to a new drive and did a clean install this time. So, with these happening all the time, it's really hard to tell if the drive is bad, or if this is the "usual" Win10 filesystem corruption problem.

    And, I did a surface test on this new drive, which ran for hours, and did not find any problems with the drive. So, in this case, I am probably safe in presuming the drive itself is not bad.
