Hello, Recently (a week ago) I have changed my motherboard, cpu and ram. At this moment I have the current configuration Corsair 550W PSU ASRock H170 Pro 4 Intel Core i5 6500 XFX R9 270X 4GB 2x4GB Corsair Vengeance DDR4 2133MHZ 120GB SSD Kingston V300 1TB WD HDD After struggling with drivers I have managed to install windows 7. After around 5 days of using it and playing games like battlefield 4, gta 5 (which had no issues) I started receiving blue screens a few times and decided I should change to windows 10, knowing that motherboard and cpu didn't really support windows 7 (thought that would help). Now, I had windows 10 running for a day and didn't receive any BSOD but Gta 5 kept crashing after a few minutes of playing, and being unable to deal with compatibility / driver problems I switched to windows 8.1. Right after installation of windows, I got vcredist 2008-2013, installed latest amd drivers, msi afterburner, which, in turn, updated direct X and I also installed all windows updates that were due. Today I received 5 BSOD in a row, with around 3-5 minute intervals. I have ran memtest86 1-2 passes with no erros, just to quick check memory sticks, although they are new and I doubt they have any malfunction. I also removed my GPU and put it back again, checking that my PSU connectors were sitting firmly (I have heard this has solved a similar issue before, gpu's power supply was unstable and resulted in errors), so as of 3 hours I didn't get any BSOD, but I doubt this state will last longer than a day or maybe even less. Mostly atikmpag.sys dxgkrnl.sys dxgmms1.sys are mentioned in BSOD, here is the minidump. I really hope someone can help me solve this problem, as after 3-4 years I have finally managed to upgrade my system and instead of stable performance I get this.
