Is my SSD causing my random reboots? (El Capitan)

Hi everyone.

I have installed El Capitan successfully, but post config is causing me a number of issues.

In order of severity; 1. Random reboots 2. Shutdown does not turn off power 3. Clover does not detect my Win10 drive on boot

Random Reboots

Probably not RAM. I ran Memtest86 for almost 3 hours, no errors. Unlikely video. Ran Multibeast, injected ATI, Rebuilt cache and fixed permissions. How do I troubleshoot for SSD if it's the cause of my random reboots?
Running First Aid from Disk Utility will trigger the crash every time

System: Gigabyte X58a-UD3r I7-930 ATI 5770 Sandisk 120GB SSD

*Used mainly guides and posts found on TonyMacx86

Thanks for your thoughts.
