MacBook freezes after RAM upgrade

テキスト:

Hello, Yesterday I upgraded my RAM from 2x 1GB sticks and added a 4gb RAM stick...so in total I have 5GB RAM.

When I click on 'about this mac' it shows up as 5GB RAM however sometimes it only shows up as 4.75GB or 4GB RAM- why am i losing a gig of RAM sometimes?

After the upgrade and I started to encounter problems. When I close the lid  the macbook would restart by itself. Sometimes when I open the lid it just shows a black screen where I have no other option but to manually restart the macbook. What could I do to resolve this problem?

I have tried resetting the PRAM and the SMC, but no change.

Thanks, Michael.
