Alt and Shift don't work on Hackintosh

[Christuss]

I managed to install Mac Os High Sierra on my pc, but there is a problem with my keyboard.

The left 'Ctrl' acts like 'shift' and Left/Right Alt, Left/Right Shift and right ctrl keys do not work!
It seems like the keys are not even registered by the computer...

I have tried all of the 'keyboard types' on system preferences and I have tried to delete the following plist files but nothing changes!
/username/Library/Preferences/ByHost/com.apple.HIToolbox.UUID.plist
/username/Library/Preferences/com.apple.HIToolbox.plist
/username/Library/Preferences/com.apple.universalaccess.plist


My PC:
CPU: i7-7700
Motherboard: MSI h270m
GPU: GTX1060
Ram: 8gb DDR4

My keyboard:
Modecom MC800M
