[Help] PC suddenly no display anymore

[fishyy]

Hello all,

I was playing CSGO, then all of sudden, black screen, no more display, monitor says there's no signal coming from the computer. PC is still on though.

What I've tried:
Changed output from GPU to directly from the motherboard using HDMI.
Tried swapping rams; using single stick
Connect the monitor to display from other PC, this concludes monitor is fine, the mobo is the problem here.
Unable to find CMOS battery to reset, I think there's a switch, but I didn't do it.

There's a solid orange LED from the mobo somewhere.

So... what could be the problem here?

Please help

EDIT:
MOBO = GA-h170-wifi - itx mobo
Monitor = U2414h

You can reset BIOS by removing the CMOS battery and replace after a few minutes.

The CMOS battery is the round shiny thing.
