Thanks for the reply Ray. I received the error before I purchased the card. And I’m still having the error with the card removed. What is the next thing to look at?

FYI – One mistake I made when putting it together in the first place was leaving off the smallest of the 3 crystals. Once I put that crystal in, it worked as it was supposed to work. And then it was when I put the card in the enclosure when I started having the same issue. I’ve used a multi-meter to look for any solder bridges and I looked with a magnifying glass and a bright light for any bad solder joints. Do you think uploading a couple photographs might help?
