monitor loosing signal - Posted In Problem Solving

today my monitor started loosing signal, one about every hour or so. connection is dvi and it is screwed in tightly and the card is inserted properly.

I have had my system on for a few days now, could it possible be getting to hot
has any of you guys ever run across this problem or have any suggestions?

I was going to restart the pc, but I want to finish the project I am working on. Also FireFox blacks out all its tabs and controls when it losses signal. I restart firefox and it is okay. I highly doubt that has to with the problem though. just wanted to note it.

graphics card is a Nvidia Geforce GT440 1.5gb
Driver version *:17:12.8026

Actually, what you're describing sounds like an overheating GPU, since your description of the symptoms indicates more than just "losing signal". With Firefox (or portions of it) going black, it's very likely that portions of the video RAM is failing to retain correct values, or possibly not having the correct values written to it. If possible, take off the side cover to your box the next time this happens (not before, as removing the side panel changes the cooling dynamics of the computer, and will change the way it acts) and see if you feel any excessive heat coming from the video card. Also note the level of dust on and around the video card and main CPU. It may be due for a good cleaning out.

Also, please note that if it IS the video card that's overheating, it may not be long before it will die altogether. When computer components overheat to the point where they malfunction, the internal damage is usually already past the point of recovery. In these cases, the card may last a few more days, or weeks, possibly even up to a year (though that's not likely) before it just plain quits, or starts populating the screen with garbage.

That's good to hear. I know a lot of folks (many of whom I met because their computers died) who hadn't the foggiest notion of how to maintain their computers. Over the years I've written several articles and/or forum tutorials on basic computer maintenance, and will likely write more at some future point.

Dang problem is back   it happened yesterday, so I restated and happened 2 more times today. I can't wait to get the computer in the new custom case. It will have much better airflow for the graphics card, so I can be sure the issue is not caused by it overheating.

I'm not sure what is causing the issue. The card is installed properly and is properly seated.
all drivers are up to date as well.

It seems to happen when when I load a web page, so I'm with you on it not being a overheating issue. I just have no way to test the temps at this time, so I just want to rule it out.

the only thing I can think of is maybe the ssd has something to do with it, but I don't see how this is possible. But when I'm booted into the other partition on the 1tb hard drive I do not get this issue. although this theory is not fully tested yet seeing that the issue is not constant.

I also played C&C today for about 2 hours with no issue, I know though that C&C is not too graphic demanding.

Have you tried the DirectX Diagnostic Tool? It may or may not help, but it's certainly worth a try.

Just hit the start button and type DXDIAG in the search box (or, for XP, START>RUN> then type DXDIAG). The rest is automatic.

here are my results

GPU core clock = 405.0MHz
GPU Memory Clock = 324.0 MHz
GPU Shader Clock = 810.0 MHz
GPU Temperature = 47.0 deg. C
Fan speed % = 26%
Memory Used = 186 MB
GPU load = 22%
Memory controller Load = 13% to18%
video engine load = 0%
VDDC = 0.900 V
