my mac keeps crashing
If I leave my iMac 27 inch mid 2011
processor 3.4 ghz intel core 17
memory 32 GB 1333mhz DDR3 running for a few hours it crashes and restarts by it self.
It never done this before, and I run diagnostics but it keeps failing If i leave it on to long unattended.
Below you can find what the mac tells me self and what Etrecheck thinks is wrong
Anyone have an idea?
