sticky keyboard

The keys on my computer keyboard are really sticky and it takes me forever to type. I actually purchased a new keyboard last year but had to get a refund because the new keyboards are incompatible with my rather old computer. My computer still runs on Microsoft Windows 95 and is also incompatible with USB. I thought about writing e-mails during lunch at work but lunch is only 30 minutes and the thought of my boss reading my e-mails didn’t thrill me. So, until I can afford a new computer, I'll have to continue laboriously punching out each key upto 10 times in order for a letter to show up on screen. In the mean time, please bear with me.
