I thought the system hdd for my HTPC was kaput, but alas, noper. The power went off in while I was out. Today is perfectly sunny. I blame Putin. I restarted the comp and it froze loading windows, then after a hard shutdown/restart I got a prompt to run windows repairs, which eventually suggested a System Restore restore, which actually worked! I'd recently updated because of meltdown and specter, so I had that goin' for me. Acronis back-up in progress . . .
