Ok, When i press right shift+ (OL> (any of those keys) it registers nothing! but when i use left shift it works... whats wrong?
Remove the key and check if there is any dust or food or anything stopping the key from pressing down all the way. If that is all clear then it could be a driver issue, so plug it into another computer and try the disfunctional keys on that keyboard.
If none of those things work and the keyboard is moderately old or cheap then it could be that the keyboard has had its days and you will need to replace it.
It might just be the way the keyboard circutry is set out, on my Black Widow it wont register W+D+H at the same time, but will register W+A+H at the same time.
It's not the circutry because it worked a couple weeks ago, but just randomly stopped working!
