Hey guys, please help me with this very annoying problem.
My keyboard stoped working properly after I installed audio drivers from Mikachu (audio was messed up thanks to windows update). Problem is very specific, basically my A, Q, 1, TAB and ; keys don't work properly (upper left corner of keyboard). Sometimes they work sometimes they don't register at all, but work when pressed with other key (e.g. shift+ or whatever else, I use numluck to be able to write properly). I'm 99% convinced it's driver problem first because to install audio drivers that work properly, you have to uninstall all drivers from ATK company, that also makes keyboard driver and also because problem solves temporarily after I delete drivers in device manager and restart computer. I tried to disable windows messing with drivers, totally disabled windows updates and installed keyboard driver from HDD but it didn't help. I can't get my hands on original driver that came with notebook, it's not on asus drivers page and also I can't find it on google.
I really think this problem can be solved by proper driver but I can't find it anywhere. Can anyone help me with this? Maybe if you have same notebook and still have original driver or point me to direction where I can find it.

Also note, it's not dirt or mechanical problem. Checked by disablement of notebook, keys are transparent, I could see dirt but used canned spray either way for cleaning.

Thank you very much for help
