keyboard probs

[Thufir]

I have a few older keyboards, some of which have keys like ( which don't 
work for whatever reason.  

Every once in a while, every few months, I have keyboard problems, where 
suddenly I can't type anything and have to reboot, even then I sometimes 
have to swap the keyboard.  I was using an ancient IBM for a few months 
until today and am now, I think, back to the keyboard I was using 
previously, which is kinda odd because I switched to the IBM because this 
keyboard stopped working.

I think that the ps2 connector is the problem.

When this next happens, is there a particular log to look in to see what 
happened?

Maybe just take off some keys and dust the keyboard?


thanks,
