down arrow key stopped working

My buddy's girlfriend was having this problem with a lappy except multiple keys weren't working. She tried troubleshooting, cleaning, canned air, checking drivers, then she called me. I asked "have you tried rebooting it?" She sheepishly said "no", rebooted, and problem solved.

Reboot is #1 on "shit to do when something isn't right" list.

 

down arrow key stopped working

My razor lycosa down arrow key decided to not respond at some point today. The other ones work and so does the numpad arrow if i turn off the numlock. Sounds like its just broken and im screwed, but any suggestions?

 

random keyboard keys stop working?

i went out today and everything was fine, i come home and three random keys stopped working, maybe more i havent noticed yet. the three key on the left side of the keyboard not working, the left shift stopped working, and the enter key stopped working, but the one on the numpad works fine. no one was home to use it, nothing spilled on it, i tried it on another computer and same deal. im gonna go buy a new one tomorrow but it makes me sad cause i loved this keyboard lol, microsoft ergonomic 4000. ill probably buy the same exact one if its in stock tomorrow, this one lasted or 4 years about. im just confused why three random keys spread out stopped working at the same time...seems very weird
