How do I make the caps lock key a third shift key?

My keyboard has some issues, who can help?

• My keyboard is completely good (clean) but now I have a little problem. Whenever I trie to make an 3+Shift, e+Shift, d+Shift or a c+Shift it basically just types nothing. I noticed that these 4 buttons are exactly on 1 line as well. For the rest everything works perfectly. Hope some of you know the answer, Cya (C was with caps-lock haha)

• Answer:

  That's a strange issue. try updating your keyboards ( right click on computer, properties.on , left side "Device Manager" search for keyboard, click the driver of it and on the top, on the icon that has a green arrow, click update driver, than it will search for them and update automatically). If it didn't solve your problem, it's probably because the keyboard has probs. see if the warranty works, if it doesn't get a new one. hope you solve ur problem :)
