I have 4GB RAM installed but PC is detecting only 3GB. I installed additional RAM many years ago and PC recognized 4GB. I do not regularly check this so I have no idea when PC started seeing 3 vs 4GB installed RAM.
Does this mean one or more of my RAM sticks is defective? How would I check? Thanks.
