You can get rid of your old computer by using an e-waste recycling company. There are many electronic companies who are obligated to take back their old goods so that they may break them down and use any spare parts that are still operable. Also, there are independent E-Waste companies where you can drop your computer off, and some will even pick your outdated stuff up for you! Try contacting your local waste management service to see if they have any e-waste days. Or you can even donate your old computer to a charity if they find it of any use.
