Ok I have a HP 866 40gig HD and 128. I'm trying to install new RAm to update to 512. I have 2 slots for Ram. So i ordered 2-256 sticks. I don't know much about RAM so I went through Crucial.com when ordering. They cross reference parts with your PC model. When i tried installing Windows wouldnt boot up and I kept getting error messages, about missing or corrupted hardware. When I reinstalled my original 128 stick everything worked fine. So i know im Installing it correctly. Crucial reassures me this is the correct RAM. So please if you can help. What am i doing wrong?!
