I have a rather old computer (dell dimension 2300). The only upgrades I've done to it are installed a CD & DVD writer and memory upgrade to the max of 1Gb. These mods are rather old too. The problem that I'm having, I had for many years but, never condsidered trying to fix it. Problem: When I watch streaming vidoe, there is a lag on the video in comparison with the audio. The long I watch, the greater the lag becomes. Q: Which component(s) needs upgrading to resolve this issue? I'm on cable modem and my daughters new laptop plays streaming video just fine so I'm quiet sure it's not my internet provider/connection.
