Q: Boot loops, graphical artifacts, and other grand adventures!

Good day!

 

I've been having some odd troubles with the iMac of the family - any and all troubleshooting attempts that I could think of and find on the web have not been of much help as of yet.

 

The unit is a 2011 27" iMac, sporting a i5-2400, 4GB of 1333MHz RAM, an AMD Radeon HD 6970M, and a 1TB HDD.  The OS installed when the issues began was Yosemite (don't recall the exact version number).

 

Issues began rather abruptly - all was smooth sailing then all of a sudden, reboots on me and enters a reboot-loop.

 

I've whipped-up a document (viewable here) detailing my issues and troubleshooting attempts, maybe their's something I missed that could be useful!

 

Cheers!

iMac
