Like the title says, I accidentally switched my desktop to second screen display only and I can't plug in another monitor because I only have the one hdmi to vga cable. I've restarted the computer and tried using Windows key + P to switch it back but it doesn't seem to be working and I'm at a loss what to do.

When this happened I was attempting to use a tv I had never used before as a monitor. I usually use a standard AOC monitor but I only have one. Not sure if that's important or not. I'm running Windows 10.

Also after fiddling around with trying to use Windows + P the keyboard will sometimes start to just make a clicking noise at every key press. After being left on like this for a while the monitor will suddenly display a blue screen with an error that says:

There was a problem with a device connected to your pc.
An unexpected I/O error has occurred. File: /Boot/BCD
Error code 0xc00000e9
This problem can happen when a removable storage device is removed while in use or is failing. properly connecting any removable storage and restarting your pc may fix this problem"

the computer then reboots itself.

Any suggestions or help is appreciated!

can you plug the cable into your 2nd video port so you can see what's on that screen.  you don't have to have 2 monitors connected to check to see if the other port is enabled.

boot into safe mode to see if that will work, if it does you might be able to switch it back
