    Unhappy Another monitor Check Signal problem

    Problem: Monitor goes blank and blinks between "Analog" and "Digital" at times, and sits at "Check Signal" other times.

    Windows XP Home SP2
    Samsung 931B using DVI @ 1280x1024
    EVGA 7900GS KO
    Gigabyte GA-965P-S3
    C2D E4300
    Enermax Liberty 500w

    Monitor will go blank at random times (not just at boot up). It seems to be checking for a signal. If this happens while my PC is up, it will freeze the PC. However, if the monitor goes blank during or before boot up, my PC will actually boot up and not freeze while the the screen remains blank.

    When the screen goes blank while my PC is up, the fan on my 7900gs accelerates and does not stop. However, the card is just warm, not hot. The card gets MUCH hotter during COD4 and HL2EP2.

    This just started happening a month ago, and was intermittent. However yesterday (I just started playing HL2 Episode 2) it became chronic.

    Nothing has ever been overclocked. Also happens in safe mode.

    Checks performed:
    -Power monitor off and on
    -Tried the 2nd DVI port on the 7900GS
    -Tried VGA cable instead of DVI in poth graphics card ports
    -Uninstalled and reinstalled graphic driver
    -Uninstalled and reinstalled monitor driver (both digital and analog)
    -Reseated graphics card
    -Tried different resolutions
    -Samsung monitor check succeeds. The "Check Signal" shows accurate colors
    -Holding the "Menu" button while screen is blank says it's fine
    -Pressing the "Source <-" button on the monitor does not correct the problem
    -Made sure all other drivers are up to date
    -AVG, Spy-Bot and Ad-Aware did not find anything
    -EDIT: It's not the monitor. I swapped my wifes CRT and the problem still happens on her CRT.

    any help or ideas are appreciated

    thanks
