it may be possible that your vga video cable is loose or not connected properly , or maybe it is getting interference by something in between like speakers or something similar electro magnetic device

If you ever find yourself squinting to read text on your monitor screen or want to fit more windows on your desktop, you may be able to fix these problems by changing the resolution of your monitor. Changing the resolution changes the size of your computer desktop.

Note: Flat-panel monitors support only a single resolution. If you change the default resolution of a flat-panel display, text will appear blurry. If you have a flat-panel monitor like the ones in the image below, the default resolution provides the sharpest image for the size of your monitor screen.

If you have a CRT monitor (any monitor that is not a flat-panel monitor) and want to increase the size of text and pictures to make them more readable, you can decrease your monitor’s resolution (or decrease the size of the desktop that displays on your monitor). If, on the other hand, you would like text and pictures to appear smaller so that you can fit more windows on your desktop, you can increase your monitor’s resolution.

Resolution is the number of pixels (the building blocks of a picture) that are used to display your desktop on your monitor screen. For example, a resolution of 1024 x 768 means that a monitor displays 1,024 pixels across and 768 pixels down. A picture that is 500 pixels wide would cover about half the width of that screen. If you decreased the resolution of the monitor to 800 x 600, the same picture would appear bigger because it would cover about two-thirds of the screen. Similarly, if you increased the resolution of the monitor to 1600 x 1200, the picture would appear smaller because it would cover only about one-third of the screen.

The following image shows the same Web page displayed on two monitors with different resolutions. The monitor on the left is set at a high resolution (1600 x 1200), so the page appears small and covers only a portion of the desktop—this makes the text harder to read but leaves room for other windows. The monitor on the right is set at a lower resolution (1024 x 768), so the page takes up the entire area of the desktop.

To change your monitor’s resolution

1. Right-click the desktop, and then click Properties.
   
   
2. In the Display Properties dialog box, click the Settings tab.
   
   
3. Drag the Screen resolution slider to the left to decrease the resolution of your monitor, making text and pictures appear larger. Or drag the Screen resolution slider to the right to increase your monitor’s resolution, making text and pictures appear smaller.
   
   
4. Click Apply to have the new resolution take effect.
   
   
5. If the Monitor Settings dialog box appears, look at your display. If you like the new resolution, click Yes. If you do not like the resolution, click No, and return to step 3 to try a different resolution.
   
   
6. Click OK.

Microsoft Windows XP changes the resolution to the settings you chose.

This problem is very perplexing. I have seen TVs with focus but not monitors. The perplexing part is why a new graphics card would solve the problem then change. It is either the cable and if you have tried more than one that would seem to rule out the cable, or it could be software setting but they would not explain why it would work for half an hour then change.The only thing that can happen in half an hour that makes sense would be overheating but I am not certain that that would affect the screen it would most likely freeze the computer so I would try a new cable but if it works for half an hour with your old cable it should keep working unless there is a physical vibration that shakes it lose and if it is screwed tight this shouldn't happen so it is very perplexing.

Yes it is very perplexing and frustrating!!! Trying two different monitors as well as two different video cards, you would think, would have solved the problem....I did try the monitor tests (as someone previously posted), but they were not much help. I actually had to come to another computer to read were abouts on the screen I was supposed to click as I could not read it on my 'problem' computer.

Does your VGA cable plug straight from the graphics card into the monitor, by that I mean you don't have anything plugged in in-between the graphics card and the monitor like an adapter of some kind? If you have used the same cable for all themonitors then it could be a faulty VGA cable. Do you have any speakers or electrical equipment near to the computer screen? Do you live near an electricity box or have overhead electricity pylon cables? You could have a poorly shielded PSU. How long has the problem been going on for and did you do anything to the computer just before you noticed the problem?

Nothing

If you have used the same cable for all the monitors then it could be a
faulty VGA cable.

I just tried changing that with the one (good computer) that is
upstairs--and it is fine--so, not that.

Do you have any speakers or electrical equipment near to the computer screen?

Computer speakers-- yes..I have unplugged and re-booted--still the same.

Do you live near an electricity box or have overhead electricity pylon
cables?

My upstairs computer works fine--so I would say, thats not it either. I did
a survey of the basement (its unfiniished, so its pretty easy to see), and
did not see anything electical that jumps out at me.

You could have a poorly shielded PSU.

(I'm not sure what this is??)

How long has the problem been going on for and did you do anything to the computer just before you noticed the problem?

Its been about 3 days or so..the yesterdays was really bad. Just kept getting
worse and worse all the time. Its the kids computer so they do "stuff" to
it all the time..
