Subscriber Joe Tann wrote with a video problem:

Terry,

I need you help. Lately my monitor picture begins to occasionally on a random basis do the “shimmeys” (very thin lines of black spread across screen in varying bunches of intervals and the lines begin to vibrate but picture on screen is still discernible albeit distorted) but screen still reacts to commands ( if word processing I am still able to do that).

Any clue as to why my screen does this? Thanks.

Joe

I wrote back to Joe to tell him that it sounded to me like either the monitor is going out or the video card is. Of course, this is a great thing if he needs an excuse to upgrade! <grin>

If you have an LCD monitor, I would suspect the video card first.

If you have a CRT monitor, I’d suspect the CRT first.

I suggested that he try to borrow a monitor or substitute one from another computer, if he has more than one computer. That way he should be able to figure out which (the monitor or the video card) is the issue.
