Hello!
Today I tried to enter BIOS randomly with my new keyboard, but when I try to enter, my BIOS just freezes. Sometimes all what loads is background and mouse cursor, and sometimes it loads everything fine but I cannot move inside of it.
I tried to reset CMOS but that did not help.
After that I tried my old keyboard, and I could enter BIOS without any problem. Then I was experimenting little bit and I got this: when I enter BIOS using my old keyboard, I can move through BIOS without any problem even with my new keyboard, even after I disconnect my old keyboard. But whenever I try to enter using new keyboard, it freezes.
What is more suspicious that it worked on my friends computer (he has different mobo though: Gigabyte Z97P-D3 + i5 4690K).
Only thing that could cause this is I updated firmware of my new keyboard (from pretty old version 47 to 75), but I do not think that firmware of keyboard could cause BIOS to freeze.
New Mechanical keyboard: Gamdias Hermes Ultimate Old Keyboard: Logitech G103
MoBo: Gigabyte Z77-DS3H rev. 1.1
CPU: Intel Core i5 3570K (idk if it can have something with it)
