Working on a KRC4 NA cabinet. Powered down in December. Restarted to test for new project last week. Went to boot up a few days ago and the panel indicated a drive failure. Swapped in my cloned backup to verify and it failed to boot as well. Was able to boot from stick to verify drives and it started running normally. Yesterday it crashed minutes after a clean boot. External monitor went dark as well. Will not start from stick and there is no monitor output. Cabinet is from 2014 with no upgrades. My first thought is motherboard failure. Any thoughts?
Thanks
