It is a compressed air spray that is used to blow dust off of electronic parts and devices. Robert suggested that your computer malfunctions may be caused by hardware problems due to a build-up of dust and other particles. Using canned air on electronic parts in your laptop does require you to take it apart.
But first, make sure that all drivers and programs are installed properly. If the problem began shortly after driver installation, try removing/uninstalling the device associated with it.
Also, scan your computer for malicious software and viruses that may cause problems with booting.
If you have thoughts about disassembly, always remember this:
WHEN IN DOUBT, DON'T!
If you are not confident about your ability to take apart and put back together a device, consult a repair technician or your computer manufacturer. Also, it may void your warranty.

I posted this question two days ago and I got an answer about canned air. I am sorry but I don't understand. I do not have canned air and I do not know what to do with it. I looked at the articles referenced and I am sure I could not take my laptop apart and put it back together again. Please tell me what I should do. Thank You!
