    So when I bought my riMac, it had Yosemite installed. I transferred the data from my 2011 iMac, and noticed that I had fairly frequent reboots. It would often reboot during the night, and I noticed this about 2-3 times per week (the computer is left on).

    I installed the beta version of El Cap, and those reboots disappeared. The computer was seemingly rock-stable, and I was happy.

    I'm in the beta program for the latest version, and ever since the last update, the computer is back to those reboots. I get that dialog "Your computer was restarted because of a problem" with the option to send the report to Apple, which I do every time.

    I did save the data reported in that window, and can post it later if someone's able to decipher it.

    I'm thinking I may clean-install El Cap, and wipe my Mac OS partition. Can I do this and keep my bootcamp partition safe? I do have a WinClone backup, but I worry that I might manage to mess it up, and have to reinstall Windows 10 along with El Cap-I don't want to do this if possible.

    I know nobody can say for sure, but I'm wondering if this is the best course of action (the clean install). It's a bit of a hassle, but I can do it if it will clear out any issues. I'd slowly add back the programs I'm using.

    I did notice that in the past, a USB3 hub I was using suddenly seemed to slow down the boot process to a crawl, and it sped right back up when I disconnected it. I bought 2 new USB hubs, and they both seem to work well without causing that problem. Other than that, I have a Thunderbolt->USB harddrive connected. I also use a Logitech MX Master mouse.

    I'd love to get this machine stable again. My old 2011 i7 iMac was always rock-stable, and is doing duty as a media server in the basement, on El Cap, without issue.

    Thanks!

    Here's the info in the crash report:

    Update:

    I posted this error report on another forum, and was told that these types of errors/reboots are most often related to memory. I looked up the memory I purchased (Crucial) and found that other riMac users had similar problems with it. I took out the additional memory, and so far, no reboots.

    What I find odd is that I had a period of time without any reboot/error issues, and it only seemed to worsen with the latest El Cap beta build. Also, I had next to no reboot issues when running Windows 10 in bootcamp. Perhaps OS X is more sensitive to memory issues?

    In any case, for now, problem is solved with taking out ?faulty? memory
