    First thing is ignore Panzke (if you see his post). There are no 'viruses' that damage
    hardware.

    As for what you actual problem is, you will have to supply more information.

  3. That's his monitor telling him that it cannot handle the output of
    the computer's video adapter.

    Have him boot into VGA Mode or Safe Mode and then set the display
    (resolution, refresh rate, and/or number of colors) to something that
    his monitor can handle. Consult its manual to determine acceptable
    settings. Reboot one more time, into Normal Mode.

  5. | Wrong.
    | They're possible with some vulnerable hardware.
    | I give you a historical example, first:
    | Back decades ago a down-to-earth simple virus could force (CONTINUOUSLY)
    | your Video controller to light up a bright pixel-cluster in CRT Monitor
    | damaging that pixel, and you won';t even discover it if it's blanked by a
    | valid image also lighting up that pixel sometimes.. Then virus moves on to
    | the next pixel cluster.

    | A modern example:
    | I won't give you - I have no right or moral desire to teach you how to
    | destroy hardware.
    | But here's a hint - malicious Firmnware can do that, I write ligitimate
    | Firmware so I cna imagine how bad Firmware can be also ceated.
    | Here's another hint - that lame hobbyist OS "Ubunutu" flavor of Linux,
    | several years ago it was found to damage some laptops BIOS.

    I don't need "additional" lessons. I'm already in school in this subject matter.

    Your description of the monitor hardly qualifies as malware causing damage to hardware.
    All you have there is normal ware and tare. Something that had been seen in any computer
    lab where computers were left on with a specific screen and no screen saver was used and
    thus there was a burned-in image on the screen. As a function of time CRT monitors lose
    their luminescence as the phosphorous hit by the electron gun naturally diminishes the
    phosphorous' ability emit photons.

    As for malicious firmware. That would be the insider threat. An employee who has direct
    access to the firmware code and modifies it to do their bidding. There was a case of
    this. If you want to burn your own EPSOM or flash your own BIOS with your own code, go
    for it. There currently is no malware in-the-wild found to be doing this.

    The closest any malware has come to "damaging" hardware has been the Chernobyl (and
    copycats) that would corrupt the BIOS and render the a system useless. However there are
    obstacles such a possible BIOS write-protect switch on the motherboard. If the malicious
    code indeed corrupt the BIOS then the either you would have to re-flash the BIOS or send
    the motherboard to the factory. But the hardware was never really damaged. It is a
    logical damage, not a physical one.

    This is caused by one of two things...

    Firstly, the graphics card is set to output higher res/refresh than
    monitor can handle.

    If so, boot into Safe Mode and adjust res to something sensible for the
    monitor. (This should be done automatically via EDID/DDC, which suggests
    the second reason).


    Secondly, hardware failure.

    Either the monitor or more likely the graphics card has died or drifted
    out of spec timing wise.

    Some nVidia GeForce cards show 'black screen of death' due to faulty
    caps. There are some fixes for this on the interweb.

    Try another monitor.

    Unplug/replug graphics card from mo/bo. Try again.

    Try another graphics card.
