Computer crashing upon boot

[snowco]

My desktop gaming computer is constantly crashing whenever I boot it up, I've been getting multiple different crashes ranging from "INACCESSABLE_BOOT_DRIVE, PAGE_FAULT_IN_NONPAGED_AREA(NETwbw02.sys), BUGCODE_NDIS_DRIVER, etc." this all occurred after I factory reset my computer. I'll tell you what lead to this decision. I got a GTX 950 superclocked from a friend, it was brand new, I plug it into my computer and every game that I played was stuttering and lagging, so my friend recommended me flashing my BIOS which I did (I had F7 and I updated to F9) after doing this I saw an improvement in gameplay but only for a short while about an hour later it started lagging and stuttering again, so I then factory reset my computer thinking maybe it was lagging because it was so cluttered, directly after factory resetting, everything seemed to be fine till I restarted my computer then I got all these crashes, so I then put my original gpu back in (GTX 760) but was still having these crashes, so then I checked on my cpu thinking maybe that was the problem I then found out my cooling system was broken so o replaced it and it stopped over heating, I then put back in my GTX 950 and factory reset it yet again (in hindsight this was a bad idea) once again everything seemed to work until my computer had to restart for an update and after it rebooted I had all these crashes happen.

Looks like all sorts of driver problems. If you upload your minidump files from C/Windows/Minidump we may be able to tell you which drivers are causing issues.

- I would start by actually removing all graphics cards and using the integrated graphics to start. See if it crashes just using the integrated graphics. Display drivers are the most problematic driver type there is.

- Consider doing a full Windows clean installation with deleting the partitions. Reset can leave things behind. As you are getting random errors, I would reinstall Windows with the PC disconnected from the Internet. After the installation is complete and you are at the desktop, observe if the system has stability issues while booting in this completely fresh state. If no failures, I would then install the motherboard drivers (chipset+Ethernet+Audio+etc) and restart again a few times. If the PC is still stable I would then install the graphics card drivers and repeat restarts. If it's still stable after that, create a restore point (and image backup of possible and a recovery USB) and I would then connect to the Internet and let Windows Update do its thing.
