    So my customer tells me it worked fine last nite. Today it is black screen.
    I get it and it powers up but no display, no bios, no boot,. I hear the fan is louder then normal.
    External Monitor not working but customer has that disabled in bios.
    A few hours later another customer of mine says his CF-52P has black screen and wont boot.

    Pull DVD and anything else reachable. Try with one stick of ram at a time.

    W10?

    odd on a 52.

    win10 update may have trashed the video hardware somehow.

    No need to answer...but WHY do people ever disable external monitor in the BIOS?....argh

    Do the lights indicate and hdd action?
