Find the paperwork
Check the documentation that came with your computer, if you still have it. Simply check the dates included in the documentation, including
copyright information and manufacturing date. The most recent year you find is likely an accurate indicator of the year the computer was
manufactured.
Check the BIOS
The BIOS (BASIC INPUT OUTPUT SYSTEM) is a piece of software stored on a chip on your computer's motherboard . This software controls the basic
functions of the computer and is rarely updated, its age is often an accurate indicator of the age of the machine, however if you have updated
the BIOS at some point it will often take on the date of the update.
Finding the info stored inside the BIOS is quite simple, however accessing BIOS info varies from one computer to the next. Normally, switch on your computer and follow the on-screen instructions, “look for press F2 to enter setup of similar”. The BIOS is typically a text-based interface you can browse through with the arrow keys. Browse all information until you find the manufacture date, or the date the BIOS was installed.
Check the manufacturers website
Go to the website of the company that made your computer, eg; Dell, Acer, HP and search for your make and model. If you don't know the model of
your computer, it's likely written on the bottom or side of your machine, You’ll normally find a variety of information about your computer--
including the year it was made.
If all else fails, google it!
Looking for press reviews is a great way of finding out the approximate age of a PC, it is normally accurate to within 1 year of the launch date
of the computer model.
Simply type the model & the word “review” into google, not much magazine editorial ever gets taken down. What you will find 9 times out of 10 is a press review done at launch. You will normally find it easily with the big brands.
