Moniter loses signal

[Nathan Hall]

For the past few weeks I have been having a problem with my moniter losing the signal from the computer the second I try to load higher-end games.  Diablo II works fine, but when I try to run games such as World of Warcraft, Battlefield 2, Joint Operations, and NFS Underground.

I switched my graphics card with my friend's to see if that was the problem, but my moniter continued to lose the signal.  I have installed new drivers for my video card multiple times and it does nothing.  I also have installed the latest DirectX.  This also did nothing.

I've been trying troubleshooters but nothing seems to relate to quite to what's happening.  The only thing left I can think of being the problem is my motherboard.

Any words of wisdom, anyone?

Thanks

Where did you get the drivers from?

nvidia.com

Step by step, describe what happens when you try and run a game?

Everything is working fine - I can surf the internet, listen to music..anything.  With World of Warcraft, when I open it the moniter loses the signal before I even get to the log in screen.  With other games I lose the signal after the splash screen.  Then I have to manually turn off my computer and turn it back on.  Today it actually did it after I tried to run a Java application.  I'm stumped.

Another thing, when I select "Restart" it will shut down and then turn its self back on but the moniter does not come back on.  When I select "Shut Down" and then turn the computer  back on it works fine.

This is the same person by the way.  I just registered.

It sounds like a ram problem to me, do you know how much you have & what the configuration is?
1 stick or 2 etc?

[sheriffnathan]

That could be the problem actually.  When I boot up it checks NVRAM every time and it didn't used to do that.

I have 1 stick of 512mb RAM.  Not sure about the speed.  I could take it out and find out for you if you like.

Swap it with your friend and give it a try.
Just take normal care for static.

[sheriffnathan]

No that didn't do it...

Also, when the screen does go black, I hear a high pitched sound shut off.  Could that have to do with the hard drive?

Remember what you did with your video drivers?
Do the same with your sound drivers too.
Gotta run, it's dinner time here.

I reinstalled both of those if that's what you mean.

1. What type of monitor are you using
2. What type of videocard are you using
3. What drivers/software is installed
4. What is the refresh rate of your monitor set to
-- Are you using ForceRefresh?
5. What resolution is the monitor set to?

[sheriffnathan]

1. I'm using a Black Elements 17" LCD Monitor, PlanoVision
2. GeForce FX 5900 128mb
3. I've used the drivers included with the card, the drivers from nvidia.com, and installed directx9.
4. 60 Hertz
-- Not that I know of
5. 1152x864

Install drivers for the monitor as well.
