    Problem:
    three interactive whiteboards fail at certain times a day they work fine until about 10:30 then problems.
    The failure causes the mouse pointer to stick to the left of the screen (Beamer projects monitor image on board) and jump eraticly in a vertical axis. The only way to stop this is to unplug the USB cable of the board from the PC.

    Attempted Solutions:
    Reinstallation of Whiteboard drivers
    Reinstallation of OS
    Replacement of all hardware (PC + Whiteboard + WB cable)
    Addition of a UPS
    Installation of PCI USB controller

    non of were anything but a temporary fix.

    Where is the whiteboard located?

    It only happens at ~10:30.. Sounds like it's not a hardware issue, but an environmental one. What happens at ~10:30 in the building?

    That's what I thought but we have had an electrical engineer in and he measured pretty much everything and got nothing.
    I should also say that ~10:30 is when it starts and continues until ~16:00, also it only happens on 3 of the 8 interactive whiteboards and these boards are spread throughout the building and aren't even on the same electrical circuit.

    Interference was raise as a possibility however when the cable was swapped with a better shielded one and removed from the conduit, the resolution of the input did improve somewhat but the problem still returned the next day.
