I recently got a new HD and have a fresh install of Windows 10 on it. It's less than a week old. I get a BSOD about once a day. They all appear to be caused by ntoskrnl.exe. Googling suggests that this is usually caused by bad RAM. I've run memtest86, and all 4 of the RAM sticks pass individually but surprisingly fail with all 4 in. If I have 3 in they all pass memtest. Any thoughts? Zip file attached as per instructions.
