It is not amd processor bug, lol. There is no such thing. Moreover, i have the same CPU and it has been running 8 instances 24/7 with no problems for months. Theoretically speaking, it is possible to get a faulty chip out of thousands good ones. BUT! Usually it is easy to diagnose it, because it would overheat, or at least one or more cores would overheat separately. There is no scenario, where one or two instances of a specific software you are running 6 times will crash

It is a rookie mistake, tho, a common one-> you change your hardware and something that used to work well before doesn't work so well, all of a sudden. Well, guess what, it is not the hardware.. most likely something on the software side bugged. Now, i supposed you've formatted your HDD when you changed your hardware, right? If you haven't, this would mean that you had an AMD cpu before; judging by your comment, that won't be the case. So you should have formatted and reinstalled Windows. The smart thing to do, is to copy your folders as they were before and reuse them without changing everything in the settings, right? Nope-> that causes quite a lot of problems. Even tho it usually works fine, i've had problems with old settings / compiled assembly folders etc. I suggest you get rid of everything and reconfigure it for like 15 minutes. That includes YAR and its folder in Plugins. Matter of fact, delete everything and redownload it from the official website. Also, i'd suggest using older Trinity (like .12 or older) cuz i had problems with loot with the .13 version. Reverted back to .12 and it works fine again.
p.s. sometimes a buggy copy of Windows might mess up your stuff, or even bad updates. There are a ton of "buggy" OSs (aka Piratebay-> 1/2 of the lite,modded etc versions) out there, i suggest you use a version of Windows you've already tested and you are sure it works fine with DB.
