Have you blown the dust out lately?
Get Temperature Monitor to see if it's heat related...

Sure sounds heat related.

Oct 12, 2015 11:54 PM in response to vidiot48170by Jeff,If your graphics card has a cooling fan, it may be clogged with dust, severely reducing its effectiveness. Blow it out with compressed air. It's also possible that the fan is barely functional or not functional at all. They're small and do wear out, usually because the minimal lubricant on the bearing dries out over time, making it much more difficult for the small fan to rotate. Blow air at the fan's blades until it spins. If it stops abruptly, the moment that you stop blowing air at it, the fan's bearing needs to be re-lubricated (if possible) or the fan should be replaced. Sometimes, refreshing the lubricant can restore it to a functional state, but not always. A well-lubricated fan should take about 3 - 5 seconds to spin down, after you've stopped blowing air at it. If the graphics card has a heatsink, then you should check for a component failure on the PCB. Look at the capacitors to see if any of the tops are bulging, even the slightest. The top of a capacitor should be perfectly flat, or very slightly concave. If a component has failed, you should replace the card.

It is not a total given, but that is where the smart money would bet. Follow BS's advice and install Temperature Monitor and if there is a GPU temperature reported, put that on the menu bar so you can continuously monitor it. I notice that it takes about a half-hour's time for my GPU to get to a stable temp after system wake. This I get from Temperature Monitor on a G5 with an NVIDIA card driving two monitors. See the screen grab from a TM history window, where the blue trace is the GPU temp.
