OK first I start eith thanks. I built my first system recently with a bit of help from this forum. System is nothing to brag about but I built it on a budget of 400.00. Anyhow no it is time to upgrade my notebook and I have no idea whwere to begin. With out looking I know it is a compaq presario 2100. I beleive it has an amd processor but which one at this point I have no idea(more to follow later). This machine is about 4.5 years old and I bought it new before I had any pc knowledge other than using the internet. What board and processor shouldf I look for? And How the hell do I take it apart to begin? Thanx again in advance...
