Problem with a quiver of the monitor

[pd123]

My Samsung monitor has a random quiver, it's rare but a few times a day. I have a fairly new Gateway. Could this problem be a video driver, video card, the computer or the monitor? Where do I start to diagnose the problem?

It would help if we knew a few extra things:

1) CRT or LCD monitor? (I'm guessing LCD, but you never know)
2) Analog or Digital connection to the monitor?

Maybe it's telling you to turn on the heat.

It's a Gateway quad Q6600 2.4GHZ processor, Samsung LCD using an analog connection. This computer does not have a DVI connection. Both are nearly a year old.

might be a bad video cable if you have a replacement try swapping it. also make sure your video settings are right.as in screen refresh rate.

Also, try using the Auto adjustment button on the monitor if you haven't already.

Lots of times it's caused by external interference, such as a motor or some other power source nearby kicking on. If you get a slight dip or spike in the power line it's plugged into, that could cause it. Or if there's a spike in EMF, like a microwave or refrigerator nearby that turns on.

If you happen to have a table fan nearby, that can also cause the quiver.

There is no fan nearby but it is directly in front of a window. I tried Gurux advice and hit the auto adjust button two days ago and it seems to have stopped. I don't understand how after months of no problems the quivers started only to be stopped by the auto adjust button. Any ideas why that helped?

[pd123]

I'm sorry to report that after more than two days without the quiver, it happened twice today.

In that case, you may want to try another VGA cable.
