10 Ways to Speed Up Your Computer Now
10. Install more RAM
The most obvious, and most effective, way to speed up your PC is to add more RAM (random access memory). You can check how much RAM you have by right-clicking on 'My Computer' and selecting 'Properties' on a Windows PC, or selecting 'About This Mac' from the menu in OS X. If you have less than 2-gigabytes (GB), it may be time for an upgrade. Even most Netbooks come with 1 GB these days, and 2 is considered the bare minimum for a Vista PC.
You can get 4 GB of memory for as little as $40 from an online retailer like Newegg.com or TigerDirect.com. Just make sure to check what kind of memory your computer takes.
