I have a box running Linux Mint I've been using as a file/plex host for about half a year to a year. Last night there was a brief power outage and I shut down both of my PCs (linux and Windows machine) using the power switches on the front. They were both running just fine on the heavy duty UPS I was running
Now the Linux box seems to give me a flashing HDD light as if it's booting/running normally, but no network. Ping to the box is unreachable, so is SSH, VNC, etc. I had been using it headless with VNC as the only control for quite some time.
I also have no video out regardless of what I plug into the damn thing. I've tried two different monitors and both DVI and HDMI ports on the motherboard. So I have no way of telling if the machine is really running.
All I can think is the board is at least... partially fried? Which is disturbing because it was on a surge protector/UPS with the other PC. I can't imagine why the power switch and HDD lights are running if the motherboard is dead. Would it power on fans and make the HDD lights flash with a burned out motherboard?
It never really made POST noises, not ever. It has a UEFI and has always started up and run silently.
This is the hardware but I don't know if it's relevant:
AMD Quad Core A10-Series APU for Desktops A10-6800K
GIGABYTE GA-F2A85XN-WIFI Socket FM2/ AMD A85X/ DDR3/ SATA3&USB3.0/ WiFi/ A&GbE/ Mini-ITX Motherboard
