LCD monitor problem **please help**

I have been experiencing intermittent video loss with my Mitsubishi DiamondPoint V71CLD monitor for some time now. It functions to a point, but it will suddenly lose video without warning. And when I reset the monitor I will only get video for a split second. The pattern continues until it finally decides to restore video for an indeterminate period of time.

I tried swapping monitors with another machine for a 2-day period and the alternate machine did not experience these problems. However, my machine had no issues whatsoever with the replacement. This leads me to believe that the issue is not with the video card. I have also run temp diagnostics on the card, and they are within acceptable limits.

The monitor in question is about 2 years old, and my system specs are as follows:

AMD 64 4000+
2 GB DDR-400 ram
BFG Tech 8800 GTS (640 mb)
EVGA Nforce 4 SLI Mainboard
580 Watt PSU


Anyway, I'm certain that this is neither the fault of the GPU or the system. However, if anyone has any ideas as to what is causing the problem, I would greately appreciate the help. Thanks.
 
Try a different cable, and use the DVI cable if you can (e.g. your Video card and Monitor have DVI output-input).

And make sure that the monitor Power Cord is seated/inserted properly, and it gets enough power from your UPS or wall outlet. Change the wall outlet too - perhaps the wires are frayed/burned.

Good luck!
 
I use a VGA-DVI dongle adapter since my monitor is a bit old. The power cord is seated properly though. I'm a bit confused though since the monitor worked on another machine using a standard non-DVI connector. It's just that the minute I jacked it into the GTS using the dongle adapter, kaput! I'll look into the wall outlet. Thanks.

I may try a different adapter, but I used the same cable on the alternate computer and it did not experience the same issue. RE: saxomophone: It does get pretty hot occasionally, but the shutdown time is completely random. It get go for 5 hours and die or start failing from a cold start.

I have also been experiencing an abnormally high number of system lockups lately. I wonder if the two problems are somehow connected. Trouble is, my temps are fine and all the tests I've run say my parts are too.
 
Definitely not the adapter. It's almost like this monitor has some slight glitch with the way my system is setup...weird as hell since all the parts are fine. I've never known a monitor to malfunction for no reason though.
