Hi Grumpy'
I do it an all for $20 but i am in Wales.
It as simple as picking the correct Ram for you motherboard details you will
find by using Belarc Advisor or your instruction manual

Disconnect power supply to your computer, Ground yourself to earth ,any
pipework radiator etc. If your are buying larger memory than you have
at present, remove slot 1 and replace with new, also you could use slot 2 &
4 with what you have at present , taking total mem to 1.5 Gig

when you reboot you might have to press F1 if asked to!
