Polaris, installing extra RAM is as easy as putting a cd in a cdrom drive. Open up the case, push the RAM into the slot (make sure your computer is turned off) turn it on again and presto, you got more RAM

I found on my dads Mobo, it was hard to get the RAM in, it may take some grunt to oush them into the slot.
