KERNEL_SECURITY_CHECK_FAILURE Windows 8.1 please help

[MentalBlank]

Hi, my PC keep crashing no matter what i do, been like this for 3-4 months no idea why. It all started when i bought nvme m.2 SSD (Samsung Evo 960) and the same day i downgraded from Windows 10 to 8.1 Pro

Now i'm having this blue screen crash even while not playing games. It happens randomly, while watching youtube,  playing games or anything. I had USB 3.0 PCI card that i bought from ebay, i even removed it and reinstalled Windows 8.1, but this wasn't the issue either. What can i do to fix this?

Run WhoCrashed to see what's causing the BSOD. Then post what it says.

All the literature I can find seems point to either a faulty hardware or driver. So I would run without any of the hardware you installed before this happened and see if things improve.

 

You're still within the warranty period, so if you can suspect something is borked, you can ask for a replacement.
