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 scratch-head
has any of you guys ever run across this problem or have any suggestions?

Hmm, well it sounds like the connection is good, so it points to the graphics card or maybe driver., possibly even the monitor, down to the process of elimination now.

But if its been on for a few days I would do a re-start first, like ya do  Smiley 

Whats the graphics card?

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.

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. Smiley

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.

Thanks for the tips and knowledge Dave  thumbsup
I will be sure to check if keeping the side cover off changes anything, if I get this issue again. Maybe I wil purchase a fan for the graphics card to be on the safe side  Wink

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. Smiley

I fixed a few computers due to family or friends not doing computer maintenance, but I usually meet a lot of people from non boat maintenance. Mostly due to mot knowing that certain maintenance was required, I'm sure it is the same with pc's. Though sometimes with certain family members reasons for non computer maintenance it is pure laziness  Tongue

Dang problem is back Cry  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 doubt its overheating Syber, if its doing it just in windows and not when gaming, but to be sure you could use some kind if temperature monitoring software, I’m not that well up on Nvidia cards so don’t know much about the software you could use, I’m an ATI man. 

You might want to check the power leads going to the graphics card, are they in there nice and tight. If the card needs two power leads they should be coming off different rails, as in not plugged into the same lead.

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.

GPU-Z will show you the temps, it’s only a small stand alone program and apparently is does support Nvidia cards.

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

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