Hello Friends! I recently purchased this computer from a close friend who completely wiped the iMac and installed Yosemite 10.10.3. (This computer is solely used for Logic Pro X with PreSonus Firepod 10) I installed Logic Pro X and everything worked fine for a couple hours. Shortly after that I installed a driver for Native Instruments Maschine and the problems started. The computer would become unresponsive for a second, the screen would flash and it would shut down (although the fan continued to run). I would do a SMC reset along with zapping the PRAM. I end up on the “Your computer restarted because of a problem”. The problem continued so I updated to 10.10.5. For about 8 days the computer worked perfectly and I thought the problem was solved with the update. I was wrong. About twice a day the computer will restart by itself and I end up on the “Your computer restarted because of a problem”. I am lost and have no clue what to do. Thanks in advance!

I did a clean install and everything has been fine since but I know it is going to happen again. I read that I needed to install Nvidia drivers but I can’t find one comparable for iMac 9'1.

OS crashes often relate to apps misbehaving. I would start off clearing the crash log so all of the old stuff is removed. Then the next couple of times it crashes save the log so you can send it to Apple as well as see what is going on. I would make sure all of the updates for the OS & all of the apps have been applied. I would also remove anything I didn’t need from startup and Login Items in the User account. You might want to boot up your system on an external bootable drive so you can run Disk Utilities on your internal drive. I would also recommend running the built-in diagnostics so see if something shows up their. To do that, when you start your system after the bong press the D key.
Go to Applications –> Utilities, and launch the Console App. Find the date and time it crashed, and post the text around that date/time. This information is helpful in deciphering what is wrong.
Have you tried updating to El Capitan? Maybe you could update your driver? Before doing either of these things, you should make a Time Machine backup.
