Could also be indicative of a system with poor airflow and the GPUs are baking. Suggest cleaning out case (if needed) and looking at airflow. Also, if you are overclocking....stop. Pop the side of the case off and run that way to see what happens.
BTW, seems this is the second GPU to fail. What was the first one? Could also be a marginal PSU not pumping quite enough power to the GPU, but need to know more on the first card.
Im shur that is not airflow cause my case temps is around 25c and cpu is at 50ish c on load.My gpu also keeps around 50 at load.Could it be the vga cables.Should i use Dvi cause i always use dvi to vga Dongle and i heard the cuts the quality out a bit
Did you try a new monitor?
If you have a choice between VGA and DVI with your system (and you only have 1 monitor), you should use the DVI connection. You will have better image quality.
