iMac 2011 Randomly Restart. Graphics Issue?
My iMac keeps restarting randomly. Often just seconds after power up and sometimes after a long time. The screen simply goes black and then I hear the boot chime. I saw several topics about this issue with mid 2011 27" iMac and I don't really know what to do.
Is this really a graphics card failure that restarts my iMac randomly? (Radeon HD 6970M) Am I stupid to go and spend $250 on another one and try?
EDIT:
I've removed my GPU card
EDIT 12-16-2017
Esta é uma boa pergunta?

Please tell us what happens when you boot using (Safe Mode) by holding down the Shift key on start up.

Boot seems to be normal. The system appear to be a little slow, for example, when I hit the lauchpad
