My keyboard is bad

Buy a new one!

yeah mine too! i have to push hard for keys like A,C,N,2! there are some cheap china made keyboards out there for only $3! but i might not buy as i'm looking for quality ones.

Right now I am having problems with the spacebar. Sometimes it works and sometimes it doesn't. It started happening after I removed my keys to clean underneath them. When I went to put the spacebar back, I don't think I put it back in right. I have to press down harder in order to make a space. It it frustrating.

Why don't you buy a new one? They are really super cheap these days. You can pick one up for about $10.00. They range in price, of course, if you would like an ergonomic one or one that has special buttons for going online, volume controls, etc. The problem is that if you spend a lot of money on one and then spill something on it, it's basically garbage. If you can't buy a new one, can you turn it upside down and shake it out? Maybe there are dust bunnies clogging it. If you have spilled things on it, perhaps it is sticky. Unplug it from your computer and give it a good wash and blow it out with a can of air. Hope that helps.
