I get this question often...What computer to buy?
I suggest you start by looking on the following website:
Next, try Consumer reports on-line and see a list of their recommended models:
I have a log-in I could go in with you and check out some of their recommendations...
First you have to decide..do you need a new computer??
If your old computer is sluggish, it might be time for a new PC. First try these steps to beef up its performance: Delete programs you no longer use. If that isn't enough, and the computer is no more than four years old, add 1 GB of memory. Adding memory is an inexpensive and easy way to upgrade your computer.
If you're running out of space on the hard drive, burn your old music, photos, and videos onto a CD or DVD and delete them off your hard drive. To add a lot more storage space, consider adding a hard drive. (An external hard drive is one of the easiest computer upgrades that even a computer novice can perform.)
Once you've cleared all your old files and moved any files to an external hard drive, run the Disk Defragmenter that's bundled with Windows. That will help your hard drive access files faster.
If none of that works, and the computer is more than four years old, it's probably time to replace it. Be sure to recycle your old computer, but don't forget to wipe your hard drive first. We recommend Eraser, available free at http://www.heidi.ie/eraser, for Windows-based computers. Apple computers have an erase feature built in :)
