IT Queries: Computer problems answered

Hi. I am using Windows XP. Once in a while after turning on my computer and then open up files, my computer would go blank (black screen) for about 3 secs. This happens when I any file inluding when I am on the web and I open a new tab or go to another website. I don’t know what’s wrong with it and it really bothers me.

This could either be a problem with your monitor, video card or the display settings.

To change your display settings, right-click the background of your desktop and select properties. The Display Properties box will appear.

In the Display Properties, click the settings tab. In the bottom left hand corner of the box you’ll find Screen Resolution and a sliding bar below it. NOTE THE CURRENT SETTING then move the bar to the left and try the 800×600 or 640×480 resolutions to see if the problem goes away.

Should you have a wide screen monitor the dimensions will be different and keep in mind changing the resolution will affect the size and appearance of the screen.

You may have to call a technician to figure out which is the best resolution for your system.

For the other two possiblities — the graphics card or monitor, these are both hardware related and it’s best to have your local computer store have a look at the problem and give you quote for replacing them if necessary.
