Hi everyone, new here and fairly new to AMD so bear with me but I finally secured and installed an xfx merc 6800xt this past week and things were all good for about the first hour as I benchmarked various games and stuff to see how the card performed. Then all of a sudden my PC rebooted in a game, not a full crash, lights all still stayed on in the case, just a quick reboot with no warnings or anything. This was Wednesday night and I've now been testing and researching for the better part of 2 days. I've uninstalled and reinstalled all current AMD drivers including chipset just in case, I've half disassembled my PC and checked connections, I've downloaded numerous stress testing programs such and 3dmark and OCCT and tested every part of my PC from CPU to memory to PSU to GPU and it passes every test. I have a few month old Corsair CX750m PSU just for reference, the whole build is only a few months old actually and it was all just fine until added the AMD GPU. I've got a few friends that are much more knowledgeable in PC's than I am and have been trying everything they can think of but nothing has worked. The crashes only happen in games and many times within the first minute of playing so well before anything could heat up, not to mention I've been monitoring everything with no red flags and the aforementioned stress tests have shown no weak points. I've got a lot of information running around my head right now from everything I've been trying here so I'm sure I've probably forgotten something so feel free to ask and I'll do my best to provide more info if needed. All I can figure is I must be having driver issues which I've been informed is something AMD struggles with. What can I do? I've spent way more money than I intended (as it always goes with PC builds...lol) and months of time due to the struggle to find parts and now all I've got is a big pretty box for surfing the internet since any game crashes it. Please help me AMD, you're my only hope. Oh, almost forgot, I've checked the event viewer and it throws all sorts of errors and critical event but none of them seem to tell me anything helpful, just that the shutdown was unexpected. I exported the log of the past couple days with those events if there is some way to attach that but I'm not seeing it. Otherwise I do have that info saved if anybody needs to know any specifics about it. Thanks.
