Two options:
1. A uC that stores the count in flash memory.
2. Battery backup.

Also, what is the max count to be stored?

Hey AnalogKid,

The max count would be 3 digits, not more than 999...

 

Is the button always connected to the computer?
Then you don't need a counter. The computer can do the counting.

Hey Mr Chibs,

No the button isn't connected to the computer...

 

This is a low cost way of doing that -
