I know this is an old thread but it came up when I googled my problem so I imagine it must come up for others as well. I had a black screen with a double beep alarm. I took it to geek squad where they told me that it was 70$ to run diagnostic and 350$ to replace parts. I took my dell home and removed the. Artery and the panel on the bottom with the small screw. Inside the memory panel is right in front of you. U click the little grey plastic holders on the side and the memory card will tilt upwards so you can slide it out. Just like an SD card. Take it out and reconnect it. My computer works like a charm. Hope this helps.
