Monitor problems

[Zilcho]

I just upgraded my motherboard and video card today. My old video card was a geforce fx 5900, and I just installed my new geforce 7800. I finally got everything working, but I have a problem whan I play games. Everytime I start up a game (have tried bf2 demo and doom 3), after a few seconds of playing my monitor will make a constant beep noise. I can still play the games but the noise is really annoying and I don't know if it is something serious. The settings for the games are nothing I haven't done before on the monitor so I don't think is has to do with the settings being too high. Any advice on this would be helpfull.

I just tried a few things to narrow the possibilities. I ran the bf2 demo on 800x600 resolution with all medium settings and no AA, and I didn't get the beep at all. Then I kept the same settings but bumped the resolution up to 1280x1024, and it started beeping after about 20-30 seconds. I am not sure if this helps, but if anyone has any ideas please post them.

You sure it's the monitor? I don't believe monitors beep. Perhaps it's your new video card -- did anything like this happen before you replaced cards? Perhaps your system is overheating and beeping to let you know. (Usually newer boards just reboot when they overheat, but some may only beep).

Thanks for the reply.
I don't know it is the monitor, but it seems like I have heard that same noise from the monitor before. Also, when the beep starts, the instant I turn off the monitor it stops.

I though it might be due to overheating, but there are a few things that don't really add up. First of all, I have plenty of air flow in may case, I had the fans cranked up while playing each of these games. Also, it is hard to believe that it would overheat that quickly, it happened withing a few seconds when the games were on high settings.
I ran 3dmark05 to see if the same thing would happen, and sure enough, within 3-4 seconds it started beeping. Just like the games however, it still was running smoothly but I was forced to shut it off because I don't want to risk frying anything. My cpu idles at around 58-60 degrees C, which seems pretty hot, but it has always been like that and i have never had a problem with it. So I think if it is a heat issue then it is probably the video card. It did seem hot when I touched it even before doing anything graphically intensive. I have never heard of problems with a video card overheating, at least without overclocking (I haven't). And if it is the video card, is there really any way to keep it cool?

You are trying to run the monitor at a resolution and refresh rate that it can't handle.

Well I have definitely had it at that resolution before with no problems. I am not sure how much of a difference a new video card would make, but it is a pretty old monitor. I would hate to run out and buy a new monitor, just to find that the same thing happens to that one too, so can anyone else confirm that it is probably a problem with the monitor? And if so, if anyone could recommend a decent monitor that isn't that expensive(I did just spend 600 on a video card) that would be great.
