Why is my Laptop running slow all of a sudden?

I bought a laptop about 3 months ago, and it has suddenly become very slow and takes a long time to load things.

It has an 80 gig hard drive and i've only used about 30 gig of it and is clean of any virus's or spyware. I've also used disk clean up to free up space. What should i do?

If your virus/spyware free, there are a couple things you can do get your computer working faster. If you using your computer for normal stuff and not gaming. You don't always need more RAM you just need to perform a few maintenance task.

First, if you haven't cleaned your registry in a while. This is necessary. Your registry holds all the information regarding updates, installs, un-installs etc. Each one of those events produces a key. That key needs your PC's resources and free space. So, if you clean your registry, you make more resources available for speed. Do a registry scan if you got more than 20 errors you should clean it.

2. Clear your Windows cache files, this is your temporary file. It can grow up to a large volume and stop your computer from using RAM properly. In a sense slow it down by preventing it from using free space.Here is how:

1. Quit Internet Explorer, Firefox, or any other web browser

2. Click Start, click "Control Panel", and then double-click "Internet Options".
