I did some minor changes in BIOS
■ I changed the POST time from 3 sec to 1 sec,
■ disabled the boot logo,
■ usb support when booting from full to partial,
■ booting only the SSD, from HDD first and SSD second (i assume that this is where i * up)
■ Did also change something about the fan speed (allow fans to stop etc.)

Either way, after these changes, I am no longer able to recieve any video from my computer.
■ I have tried to clear the CMOS both with moving the CMOS Jumper, removing the CMOS battery, and doing both at the same time
■ I have also tried different video outputs - HDMI to DVI (GPU), HDMI to HDMI (GPU), HDMI to HDMI (Mobo)
■ I have tried removing the GPU and only using the Mobo as output

Any additional information:
■ Neither my KB, nor my mouse is lighting up when powering on
■ The fans start spinning
■ The GPU LED light is lit
■ The onboard LEDs are being lit during boot, but they turn off after 5 sec. It goes 30 sec, and then they are lit for another 5 sec. This goes on in a loop
■ My Qi-charger is working fine, even though the desktop is powered off (or on)
■ My motherboard is Asus Sabertooth Mark 2 z97, and the computer have been perfectly fine for 6 months, till I decided to do these changes in the BIOS.

Any ideas for fix?

<Language, please. Thanks>

The I/O was turned to O and the power cable was disconnected from the PSU. How come?

It is. After i disconnected the PSU from the power, I removed the battery, moved the jumper, waited 30 sec, moved the jumper back, and placed the battery in the mobo again. Tried to power up, but no video signal.
 
What was the reason why you changed the settings? Setting USB support to partial probably should be done last when you know that everything else is working fine. It may be normal for the keyboard and mouse to no longer work at POST as that's probably what you wanted to achieve in order to save a second or two when powering on the system. At this point it looks like the CMOS doesn't get reset; contact Asus support and if they can't help, then RMA the motherboard.

Honestly... I was trying to reduce the boot time by maybe 1 or 2 seconds. It's not like it was an awful lot in the first place, 12 seconds or so, but I was trying to achieve the absolute maximum boot speed. I'll email Asus as my first priority in tomorrow morning. Thank you for helping out, though! :)
