I've been given some details about a computer, want to know about what year you may think it's from...

Question

Processor: AMD 64 Bit 2800

52x CD ROM Drive

80 GB Hard Drive

512 MB DDR RAM

up to 128 MB 3D Graphics

5.1 Sound Adapter

Fast USB 2.0 Ports

Answer 1

Unfortunately, you did not include the operating system

The key from what you have given is can the RAM be increased

If the unit has Vista, you want at least 2G of RAM

Answer 2

Since it is DDR and not DDR2 ram that makes it a socket 939 or older. USB 2.0 is relatively new though so it may be one of the last 939 Mobo's made. I would put its age at 3yrs? If you were to run a free app like CPU-Z (available for free from link below) you will find out the model # of your motherboard and it would help narrow down the date of manufacture.
