Power Supplies - If your computer is not powering up when you push the power button, a new power supply may fix the issue.
Motherboards - Either upgrading, or replacing a defective board.
Memory - More RAM can add increased performance to your computer.
Hard Drives - I recommend at least two hard drives in a computer. A secondary hard drive makes an excellent storage device.
Video Cards - If you're a gamer, then a good graphics card is a must!
Optical Drives - Want to burn CD's and DVD's but can't? Then upgrading to a burner may be an option with your current computer.
Network Cards - Want to get on Hi-speed Internet? An ethernet card either wired or wireless is required.
Printers - A computer is not complete without a printer.
Scanners - Scanners are great to get hard copies of documents and pictures onto your computer in digital format.
There are so many peripheral and internal devices on the market today, that I can't begin to mention them all here. But, if it installs on a computer, then most likely I can install it.
