keyboard keys randomly not working

[therrd]

Hello I hope someone has a good answer. My Acer Aspire keyboard is having issues. Randomly keys will not work with easy touch. For example the e key will not work as i type normally. If i press the key aggressively suddenly it will work and put three e's on the screen. If I open a program like this thread for example and begin typing, and keys are sticking constantly. After a bit of time passes, everything starts to work great?? What the heck?? HELP!....

sounds like a dirty keyboard. get a can or air or use an air compressor to give the keyboard a blast of air.
