Hey guys,I'm new to the computer world so please be patient.I have an older laptop and was told I should upgrade hard drive and memory.The hard drive questions have all been answered but, I have no idea as to how to buy a memory upgrade.I have an old Compaq Armada M700 with a 224mb memory,366mhz processor speed,I think. Could I upgrade to a 512 ? If so what specs do I use to search for one ? Any help would be greatly appreciated. Thank You, Anthony Lackey.
