I previously created a thread concerning this issue, and prematurely listed the issue as Solved. After 24 hours and a lot of doing what would previously cause the BSOD, I started getting crashes from previously benign things, like reading articles on the internet. My previous post was as follows:

2 weeks ago I upgraded my desktop. I replaced my Nvidia GPU with a Radeon r9 290, uninstalled the Nvidia drivers, and installed the AMD ones. I also imaged my old HD and restored it to a new 1TB Western Digital, and upgraded to a 750 watt PSU. I've since been having BSOD issues where my computer freezes for about 5 seconds and then restarts.The BSOD always happens when playing games or watching videos, whether it's Youtube, Netflix or from my hard drive. Viewing the DMP files in BlueScreenView suggests ntoskrnl.exe is the culprit, but after much googling, I haven't found a good solution. I've done 7 passes of Memtest86, two chkdsks, two SFCs, and reinstalled my graphics drivers three times with no results.

So I'm totally stumped. I can upload the dmp files if needed, but I'm not sure where to upload them to. Any suggestions would be greatly appreciated.

Full specs:
OS: Windows 7 Home Premium
CPU: AMD FX 8320
GPU: HIS Radeon r9 290
Motherboard: GA-78LMT-S2
RAM: Ripjaws F3-10666CL8D
PSU: Rosewill ARC 750
HDD: WDC WD10EZEX

I reset my BIOS as per someone's suggestion, and the problems stopped for over 24 hours, even while gaming. I left a movie on overnight to test that, and my computer did not restart itself, so I considered the problem fixed. Here are the new DMP files, along with some of the old ones.

There are more DMP files, these are just the most recent ones. If more are needed, let me know.

Thank you so much in advance for any advice.
