yh I've tried pressing F8 and F12
and the keyboard doesn't work fully in the first place
I believe you might have fucked up your pc
Maybe to test if windows even loaded try getting to sticky keys
But apparently not even windows loads
If you have speakers up and running
I've replugged the keyboard in different ports and still it won't work
new pc time

at least you only need to rebuy one part
unless using a red key to remove everything will fix it
maybe, but it could also be the CPU
since without CPU it is essentially braindead
