Your HP ProDesk 600 G1 is having issues with posting and turning on repeatedly after being off. After being unplugged for a while at your grandparents' house, it stopped working entirely when you returned. Now that you're back home, it still doesn't function properly.
There was an issue where the CPU didn't connect properly to the socket. I had previously reinserted it, cleaned the contacts afterward, and then powered it on last night.
