how to fix my slow computer, and constant freezing?

This computer used to be faster, without freezing. The computer is dusty and im scared to dust it because i could damage it. i can replace parts, but i dont know anything about computers, and what part to replace. I also have windows 32 viruses that i dont know how to get rid of, and microsoft security essentials cannot get rid of.

More about fix slow computer constant freezing
  1. since you just posted this - i will come with some recomandations - but likely wont come back to follow up on them - so others must do that for you!

    1. post the names of your viruses and ppl can help you.
    2. to my knowledge dust does not slow your computer down (?). What does is a blocked cpu cooler - it will make your cpu hot and throttle down. I got a easy trick i use myself. Get a vacum cleaner and a straw. Hold the front of the hose to get the straw to do the vacum (no need to get a strong vacum - just a little is good enough). Use the straw THOUGH the fans to clean the top of the grooves - do NOT get the fan to spin up - hold it with your hands if you need to.

    good luck - hope this gets you started
