I am facing a weird issue where all my back USB ports are dead. There has been a power loss and after that, the USB ports are not working anymore. The DVI output is working.

What have I tried:
- Reset BIOS -> did not help
- I used different ports -> did not help
- I tried with keyboard and USB -> still not working
- I luckily have a spare PSU to try with -> did not help

I am waiting for PS/2-USB adapter so I will be hopefully able to use my PC.

Anyone had a similar issue before?
