Do-It-Yourself Story

Diagnosed as main computer board. The new board solved the issues. The repair video was very helpful and I installed the board with only one difficulty: in the video, after installing the several plastic inserts in the new frame, he turns it upside down and joins the two halves. Looks simple. It when I turned it over all the pieces fell out. They wouldnt' stay in. I eventually figured out how to make it work, but I looked at the video again and I noticed that sequence was not shown--did he have trouble too? While I'm happy with the result I'm also annoyed by the fact that when I first looked up the part the price was 131 dollars, but then I was told that part was incompatible, and the new cross-referenced part, tho the same part number, was a higher price. Seems like bait and switch.. However. The part fixed the problem and the part was delivered quickly.
