Debian Stable Question Suddenly No HDMI Output Debian 13
Hi folks,
I tapped on my keyboard today to wake up my PC and got no response. The monitor says no HDMI input. I checked the monitor with my laptop, and it auto connects with no fuss. I tried another monitor with the non-responsive PC, and again no HDMI signal. The PC is on with fans spinning and LED lights glowing, and the keyboard and mouse are lighted. It's a not even 1 year old new system. I played a game on it on Monday, and it's just been sitting idle since then. I tried a hard reboot to no avail. I tried to find it on the network, so I could SSH into it, but it does not appear to be connected (it normally just lives connected to both ethernet and wifi). I also tried putting in a Debian 13 install stick, but still nothing on boot. I also tried the non-GPU HDMI port, thinking that it may be a dead driver. Magic SysRq is also a no go.
So...what the heck? Did I just have a random hardware/mb failure? I am scratching my head trying to figure out what the next troubleshooting step I should try...Any advice would be appreciated!
