My desktop computer monitor flickers once quickly every 1 to 2 hours, the cause?

  1. Hello. For the last few days now (never had this happen before), my monitor on my desktop has been flickering. When I say flickering, I mean that it flickers once quickly. The color of the flicker that I can pick up with my naked eye is just slow enough so it looks black in color. The flicker is about a half a second. This occurs very random now. It was occurring about every hour or two. Just last night is was happening about 5, 10 or even 15 minutes apart. Always just one flicker with 1/2 second in duration. Nothing happens to my programs that are running after this happens. System appears okay.

    Now, during last night's flickering, the desktop area of Windows XP (everything above the taskbar) was all solid black for less than a second; at the same time the taskbar's border lines ("Start", the buttons for open applications, and the system tray) were highlighted in a wide light gray boarder with a black area inside each area. After that brief second, it all came back to normal after flickering back to normal as if the images on my screen were generating back to normal. Now today, it is just back to that super fast flicker again every hour or so.

    I'll add that if I am reading a long article online and I have not changed the screen for a couple of minutes (no scrolling, mouse, or even keyboard contact), it seems to happen a little more frequent like last night.

    I know it could be to a lot of things, but I am sure some of you experts are quick to jump at what actually may be the culprit from experience or knowledge. Please share with me your thoughts and ideas.

    How severe is this and could it get worse? Will I need to do something soon like?

    Now I know you may need some data about my system to help you. I used Belarc Advisor for the data. I have quickly checked the data you needed. So far looks accurate.

    Not in the data: Let you know that my system is custom made. Motherboard: ASUS P5Q (standard version board).

    Hope this helps.

    Thank you!!!

    Hello reconsentry. Thanks for your reply. I see what you have responded in the way you did... ...I have an Nvidia graphics card and not ATI. My driver is Nvidia installed. I have the 9600 GT. I know it states an ATI item in my list. It is used for my TV Tuner card some time ago. The card is not active and so is the driver. I know Belarc Advisor goes overboard with system data. I have no conflicts or issues with my Nvidia to date. The Nvidia driver is fairly updated.

    Could you solution be applied in the same manner to Nvidia too?

    Thanks!
