Actually quite a few people
are having similar issues. I think the reason "everyone else" isn't complaining is that there are distinct factors to be met.
I've isolated most of my own factors and fixed them by putting my usb 2 stuff on a usb 2 bracket I purchased and also by removing the SSD from the SATA3 port. No more BSOD! The BSODs were the worst part of the equation, now that they are over I have to work towards the last issue I'm having.
I would hazard a bet though that if I instructed someone to do A, B and C with any z77-UD3H, it would BSOD as well. Once you can replicate certain factors, I think it will happen on any D3H, UD3H and UD5H but I will never be 100% certain unless I can find someone to help me test. But I'm 90% sure because of issues others have posted.
As an example the most annoying thing right now is that the VIA VT2021 audio drops out and in when my Logitech G930 headset usb key is plugged in. Because of the dropout, the G930 is set as the default device which is annoying as hell because then I have to set the VIA as default, pretty much every single time I reboot OR I have to unplug the usb key until I need to use the headset. In order to find out if this is normal for the board I need to now find someone with a G930 to see if they have the same issue.
So is the board defective? /shrug. I'm not saying it is not but I'd rather do my homework and figure that out to some extent before I give up a nice board. I'm guessing if I gave my board to someone else and they threw in a spinner, cheapy keyboard and mouse, it would work fine. Likewise, if I did RMA the board for a replacement, I would likely get the same crappily incompatible (to my system setup) board I have right now. I'd spend time removing it from the case, $15 to mail it back to Newegg, time without the use of my PC and then possibly
have the same, exact problems with another board. So, just taking my time and doing a little more research.
I'm going to spend 1 more week with it and see what happens.
