Hello, today my keyboard decided several keys would change roles. Letter t I have to cut and paste. If I tap it it tabs out or every few taps will pRINt A t. CAPS LOCK IS PLAYING UP ALSO. THE LEFt DIRECtION tO CAPS LOCK AND BACK SPACE PLAYS BETtWEEN BACKSPACE AND NUMBER SIX, NUMBER SIX DOES NOtHING. THESE KEYS HAVEN't JUSt CHANGED, tHEY ALtERNAtE A BIt. IS MY KEYBOARD FRIED? I HAVE NO OtHER tO tESt OR tRY
PLEASE HELP!

If you get characters out just by tapping on it, I would suspect a loose connection somewhere. The easy one to test is where it plugs into the computer. Otherwise, you'll have to take the keyboard apart and look for a mylar circuit similar to the picture attached. The tab part should plug into a circuit board connector. Gently pull it out and plug it back in. Note that sometimes there is a locking mechanism on the connector, so be sure to look for that.

Best of luck.
