My 7950 causes no signal on monitor

[reubenno]

Hello, I have a fairly big problem.
My Sapphire 7950 is causing a signal loss on my monitor any time I try and game with it. I can launch games but as soon as I do I lose signal. The GPU is overclocked to 1100/1470 but it is stable as it has been used like this for three months. I have put the fans up to full but the GPU is staying below 65 degrees. Are there any fixes for this? I am downloading the latest AMD drivers so I will update the post when they have installed but I do not think that will solve the problem.

Thanks

What game are you playing? Did you build a customer profile in AMD CCC? did you recently change your monitor? did you change the settings in the game to an unsupported video refresh rate?

So far I have tried Crysis 2 and Sniper Elite V2 with both causing loss. I am on the same monitor I used at the start and I have not changed the settings. Thanks for the reply

I would remove the overclock on the GPU and try to load the games, one thing to note is if the VRAM on the GPU has taken to much stress over time this can result in a diminishing effect on GPU overclocks and eventually lead to VRAM failure. What is the typical range on the VRAM while idle and gaming?

Removing the overclock does not help in crysis 2 but I am running crysis one on the OC'd card right now. At idle I use about 78mb of ram and in crysis 1 I use one 1GB
Thanks again
