GeForce 6800 Gt, Unusable signal

Recently whenever I play computer games my My monitor will go blank for a few seconds then give me the message "Unusable Signal". This usually happens about 15-30 minutes after playing a game. Afterwards, I am forced to restart my computer. My video card is a GeForce 6800 GT, and my monitor is an NEC MultiSync LCD1760v. The problem only occurs when playing games with high requirements, even when the all the options are turned down. I never had the problems till recently. So far I have tried downloading the newest drivers for my video card and making sure the cable from video card to the power supply didnt have any other devices attatched to it. Neither of these seem to have solved the problem. Any help would be greatly appreciated.

Hi, I have an Acer Aspire M3820 with Windows7 and a Geforce GT320 graphic card. Recently I installed an online game with pretty high system demands, but my current configuration should do just fine. So at...


It sounds more like your video card is overheating, and stops sending output to your monitor. Double check the card, make sure the fans are running correctly. From what I can tell, the Geforce GT320 highest temp seems to be 105c. You can use RivaTuner to keep an eye on your temps. You can download it here.

Throw some more fans in the case if necessary.

I am having problems with my nvidia geforce 6800 gt. When i turn on my pc everything is fine but whenever i play games for ex. Bioshock or counter strike source my pc screan turns off and says no signal....


i suspect youyr graphics card is heating up and shutting off to prevent damage. windows will also shut it off but usually repaorts that it did. here is my reccomendation:
1. open side case and place a fan right nest to it. if this makes it work then heat is definitely trhe culprit. if so install a video card cooler or another exhaust fan.
2 turn all the graphics options down on the game. shut anti aliasing off and all options to minimun. then try to play if it still shuts off then your card may be on its last leg from over heating. the 6800 gt was ok when it came out but todays games require more. in fact the newer games won't run on a 6800 gt.
the big thing is heat. the standard 6800 gt just doesn't get rid of enough heat. in fact the 9800 gt i had overheated and burned out. i stay away from gt and now use gtx cards. they have a better cooler and ususally the vent outside of the case.

You may have adjusted the video settings of the games to higher settings that may not be compatible with your card.
While in a game press the windows key and D together.
If you go back to desktop it means the video settings of your games are to set higher than your card can support.
Hope this helps.
For further assistance please feel free to ask me.

GeForce FX 6800 Graphic... Problem


Hi,
you should look for updated drivers - www.nvidia.com
If the problem persists, it might suggest a hardware problem.
It is a good idea to test the card in another machine and see if the same problem happens.(maybe in your friends computer ?)

Is my Motherboard compatible?


Try to find out what the AGP voltage is on the motherboard.
Some graphics cards use 1.5 volts and some use 3.
If it's a 1.5 volt AGP slot and you plug a 3 volt graphics card in, it either wont work or you could permanantly damage both card and motherboard.

Is my Motherboard compatible?


Probably not. There is not quite enough information in your post to really help, but from what I'm finding on the GeForce 6800 GT, it is only available in PCI-Express and AGP 8x (AGP3.0) Versions. Your motherboard only supports AGP 1x, 2x and 4x (AGP2.0) cards.
