Hello Everyone, So this weekend I attempted to turn on my Imac and I was able to use it for about 5 minutes then out of no where it just simply restarted on its own. Now every time I try to turn it on it just keeps going in a cycle of restarting itself. At one point I did leave the Imac alone for about 30 minutes and then I was able to turn it on again and use it for about 2 minutes before I restarted itself again. Once again going through the same cycle of just restarting itself again. About two months ago I did increase my Ram from 4GB to 16GB. I'm tempted on putting it back to 4GB, just to see if that is the issue or not. Any recommendations?
