    I keep meaning to post this, and since it just happened, I'm going to do it now. :)

    Once in a while my desktop (eMachine) will spontaneously "log off". After doing that, the screen (BenQ LCD) will be just a black screen with the mouse pointer on it. I can move the mouse and see the pointer move, but the computer will not give me the startup screen/desktop or anything else. The only thing that seems to get it back off of this screen is a hard reboot, which I dislike doing.

    My tower doesn't blink or otherwise indicate that it's "sleeping/hibernating" (indicated by a blinking blue light and a blinking yellow light respectively), it shows the solid blue light as it does when the computer is functioning normally during usage.

    What can I do to stop this from happening again? What is causing it? Thanks for the help--I'm sure it's not a "major issue", but it IS an annoyance. :rolleyes::(

    Farmgirl: I suggest you take the side off the tower and check carefully all the capacitors on the mobo to see if any are bulged or leaking.

    Next, using Device Manager, try updating your video driver, or use Windows update Custom Scan to see if there is an updated driver for your card. BTW, if you have card installed in a AGP or PCI slot, check the capacitors on it, too.

    You can also run a Memory test as a bad memory stick will give you probllems similar to yours.

    Good luck.
