When I type the letters look like symbols. Any suggestions?

I followed the directions for the safe boot again. This time the screen did did come up asking me to enter my password. Only problem, when I entered my password it did not sign me in. I am pretty sure I am typing the correct password but as I am typing (even though it does not show the letter-it shows asterisks) it is probably picking up only capitals instead of the lower case letters that I am trying to type? not sure

Then I rebooted normally and tried to enter my network password, it says incorrect. Then when I go to network to try to enter my network password again it says "enter the 64 hexadecimal characters"

I think so, it's my old MacBook Pro, probably snow leopard...

It is either leopard or snow leopard.

I use Verison Fios and my password is 7 characters... It is not encrypted on my newer Macbook Pro...

I think this old one needs a new mother board...

I tried following the suggestions in the support article but it did not work.

One thing that I see that is different from my current MacBook Pro than my older MacBook Pro is this:

On my OLDER MacBookPro (that is NOT connecting to the internet),

if I go to TextEdit, then click on TextEdit in the upper left hand corner, point at the "Services", the top choice is ChineseTextConverter...

On my CURRENT MacBookPro, it does not say ChineseTextConverter when I follow the same TextEdit steps...

I realize this most likely does not have anything to do with my problem...

I just do not understand how everything appears to be working on my older MacBookPro EXCEPT it is typing strange characters when I type on the keyboard.

What I am thinking of doing, is going to an internet cafe just to see if my computer will connect to their internet service? Do you think that might be helpful?

Thank you for your help.

I also do not understand that when I first typed my network password it typed the correct associated keys with the exception of recognizing each keystroke as if the Caps Lock was on (when the Caps Lock was not on). But when I typed anywhere else it consistantly typed strange and but consistently different characters for each key (like each key has a different strang character instead of a different letter)...
