Hello guys,

I have an 820-3299 that originally had a question mark issue. We decided to switch out the hard drive with an SSD and when putting it together, it no longer wants to boot and has 3 beeps, few seconds pause, and 3 beeps again until I power it down indicating RAM detected in bay but unable to use it? I've tried known good working RAM and still the same. I completely removed all RAM sticks and it would give me 1 beep indicating no RAM in bay. This SSD upgrade involves removing the board in order to remove the hard drive unfortunately so I am unsure if something had happened during the removal, but I'd like to troubleshoot the logic board and need to know where to start.

Thanks in advance for the help.
