Monitor randomly goes black for one second at a time

I have a relatively new monitor and computer system (bought May 2003) and in the past few months, the monitor will go completely black for about one second and then come back on randomly throughout the day.

It will do this completely randomly and sometimes will not occur at all for a week or so, but then without warning, will start up again, going black many times throughout the day. The diagnostic lights are all on green normally, and since the screen goes black for only one second, I don't have time to check the tower while the monitor screen is black.

The power light stays solid green with no change when the monitor goes black.

I've checked the cord connecting the monitor to the tower and it's as secure as I can push it in on both ends. A friend recommended that I get a new cord (he said it would the "HD15 (plug) SVGA monitor cable"), but I wasn't able to find anything like that on the Dell website.

Does anybody have any suggestions for what could be causing this problem, and how I can fix it?

Thanks in advance for any help.

i just called tech support.  they suggested to press on the ok button on the monitor, then using arrows go to factory settings, then press the ok button on yes.  i still don't know if this will work, but it's worth a try.

I'll try it, but when this first started happening to me, I called Tech Support, and they told me to do that, and maybe for a month or so, I didn't have any problems, but then it started up again.

So if that's a solution, then it's only a temporary one.

I have the same issue.  Contacted Dell support.  I was also told to reset my monitor to factory defaults.  Did this, it did not help.  I've also reinstalled my video driver & monitor driver.  Turned off all power save features and screen saver.  My computer is less than a month old.  Have you been able to find an answer?

Nope, still no answer. I guess Tech Support really doesn't have an answer on this. It's a shame, too. Maybe it's a faulty cord or something, and if so, we should be able to get it replaced free of charge.

I have had the same problem for several months, and am convinced it started when I installed one of the Windows updates, but am not sure which one, since the problem is intermittent.  I just think it is some kind of software conflict.

Hmm. That's an option I hadn't thought of. Does anyone have any idea about what sort of Windows update would do that?
