Possible GPU Problem?
Hello all,
Last evening as I was working on my MacPro 5,1 I noticed that the MP 4,1 had shut down. A few weeks ago I noticed a slight clanging sound from the MP 4,1 and discovered that it had shut down then as well. After having some GPU issues with my MP 5,1 a few months ago, which I eventually solved with a used unit from OWC, my first thought was that perhaps the GPU in the MP 4,1 had also died. Now when I press the power button the MP 4,1 will not boot and the red light from the GPU area stays on instead of simply flashing as usual. Perhaps another sign of a faulty GPU, not sure.
I then shut it down from the power bar.
I’d like to get some opinions on this if possible before I order yet another GPU. All replies will be much appreciated.
