Window expands and shrinks

[garebo]

running win xp pro with a 22inch monitor, supposedly a trinitron, says Compaq on the front. When i have any window open it all of a sudden shrinks a bit and then later it will go back to the size it was, which makes the "x" or close feature off the screen. I have to kind of guess where the x is to get out of that window. Also, the whole desktop does the same thing, shrinks a bit then gets a bit larger, then shrinks. I am getting so used to it that its not the end of the world, but if i can stop this, it would be helpful!

I have one 5 foot svga cable, a good one. I tried changing the cable, using an older vga cable and its the same and also kind of shimmies so its actually worse so i changed back to the better cable. I am not using an extension cable at all.

1152x864, 32 bit color, display\dpi setting is normal size 96 dpi, onboard intel extreme graphics, in the monitor section it says the screen refresh rate is 100 hertz, but when i go to the intel extreme graphics it says the refresh rate is 60 hz, and i notice it will allow the setting to be changed up to 85hhz at the highest.
I got this monitor used and it is older so i dont know how much use its had. I did degauss it when i first got it.

I am not up on this so can anyone tell me how i might fix this?
thanks

Offhand, the symptoms you present sound like a monitor or line voltage problem. Randomly changing screen size is usually indicative of voltage fluctuations, either at the mains or in the monitor circuitry. Do you have another monitor to test with your PC? And do you have any idea whether your line voltage is fluctuating or have a UPS that you can plug it into?

I forgot to mention, other monitors dont do this, and my cpu and monitor are connected to a ups. One of the reasons for the ups, besides the obvious,is that we have very dirty power in our area, lights dim, sometimes who house goes out for a second, sometimes only one line goes out for a second, things like that. My computer used to turn off once in a while before i installed the psu, now its only once every month or two.
So perhaps that is the answer, poorly regulated, dirty power.

It's certainly a possibility, particularly with such a large monitor. The only suggestion I have -- and it may not be feasible -- is to ask someone in a different area to use the monitor for a while to see if he/she experiences the same problem.

lol

This is a home setup, and if you saw a pic of the setup with all the cords and stuff, it would take a half hour to get the monitor out and another half hour to put it back in!
I suspect its what i said about the dirty power, coupled with the size of the monitor itself, draws a lot of power.
But i didnt think about the bad power issue until after i had started the thread. I only got thinking about the dirty power around here when "dirtyisland" posted and said the magic words "voltage fluctuations". That made me think of the dirty power we get here. As a result of your dirty power i brought in extra ups's, i now have 3 of them here to run all my stuff. I just didnt think of the dirty power as a part or all of the prob, otherwise i wouldnt have even posted.
Some ups's can be adjusted to be sensitive or tolerant of current issues, there is maybe a place i can start.

Unless, of course, someone comes up with another idea.
thanks
