I look forward to hearing from you.
Sure, I'll PM you my email address. Please, feel free to email me and we can chat then.
Regarding the issue with USB 3.0, I have not been able to replicate it. I, as you, was curious to test USB 3.0 immediately after I installed the system and updates. I also updated BIOS to the latest version (not sure which, as I am currently not at my desk), if that helps. I have had no stability problems with that port, or any other USB port. It could be your board, especially that it is exhibiting other quirks. But it could also be another, seemingly unrelated component. It's awfully difficult to troubleshoot such quirky issues.
I had only one issue with this board, and that was the Patriot Gamer 2 Series RAM (4x4GB), but the errors were not indicative of RAM explicitly. For example, I couldn't install Windows due to a DVD drive failure, but I also couldn't install it from a USB stick, with the same error message. I have immediately swapped the RAM with one type of Corsair, no problem; then another type of Corsair, no problem. So I knew it had to be the RAM. I bought Kingston HyperX Gray series and it works perfectly. Not sure if the ram was bad or not compatible.
I was afraid of potential problems with my OCZ SSD (Vertex 2), but it works better than in any other system I've put it in. True, with each firmware update, the SSD has worked more reliably, and now, it is finally rock-solid. This is why I decided to stuck with it for this build, despite faster SSDs being available. The reviews of the Vertex 3 scared me a bit.
Hope that helps. My advice would be to not waste any more time and replace the board, perhaps with another model altogether.
