Windows 10 BSOD in Normal Mode but Stable in Safe Mode

I installed some NVIDIA GTX1070 drivers around 2-3 months ago, and a week later I began to experience BSODs, usually MACHINE_CHECK_EXCEPTION, IRQL_NOT_LESS_OR_EQUAL, and CLOCK_WATCHDOG_TIMEOUT. I initially thought it might be because of my overclock settings, so I reset my BIOS settings, but the BSODs persisted.

I then suspected either a CPU, motherboard, or RAM hardware issue, so I tested my CPU on my friend's z270 motherboard, and ran VR and prime95, which had no errors or crashes. I ran memtest86 for 10 passes, again with no errors, and I replaced my motherboard from the Gigabyte to the MSI motherboard shown in the specs. Still BSODs.I decided to try running in Safe Mode, which miraculously had no BSODs for over 2 hours, over the course of which I ran an hour long YouTube video, and ran prime95 for an hour, with no errors or crashes.

This made me think that it was a driver problem, so I wiped my SSD with Samsung Magician, and attempted to clean install windows using Windows Boot Media.Interestingly, the Windows Boot Media still had BSODs (keep in mind that at this point, the SSD was blank, and the HDD was unplugged).

I tried running Windows Boot Media with both the SSD and HDD unplugged, but still had BSODs. I suspected the Boot Media might be bad, so I first ran sfc /scannow, which said there were no errors with the Boot Media. I also tried running Ubuntu's "Test on this computer" as well as tried to install Ubuntu (with all combinations of HDD, SSD, or none plugged in), and still had freezing.

At this point, I'm completely lost on what to do next. Since the computer ran fine in Safe Mode, the issue has to be a software/driver problem, but I have no OS installed, and the problems persist even without an SSD or HDD plugged in, meaning its a hardware problem, which makes absolutely no sense. Does anyone have any ideas?
