Hello folks. I have an unhappy iMac (Retina 5K, 27-inch, 2017) 40Gb RAM 10.15.7
Problem is random restarts. First symptom is the mouse freezes then about 30 seconds later the computer turns off and restarts. This happens enough to be very annoying, and has occurred whilst I was drafting this message. The problem first occurred after I had transported the computer, screen down, on the seat of my car. No physical external damage is apparent. Problem does occur in Safe Boot mode, though not as frequently as in normal mode. EtreCheck shows nothing out of order Rebooting into recovery mode and running both Disk Utility and reload latest operating system have been done. *** MCA Error Report *** CPU Machine Check Architecture Error Dump (CPU: Intel(R) Core(TM) i5-7500 CPU @ 3.40GHz, CPUID: 0x906E9) CATERR detected! No MCA data found. I had assumed it was a hardware problem triggered by moving the machine but nothing is showing up in any errors that I have seen. I have removed and replaced the RAM. When running, it functions normally as expected. Any thoughts on what else I could do before taking it to the doctor? Which doctor is recommended. I live in Duncraig area.
