Why am I getting a Kernel Security Check Failure at random times?

For about a month now I think, I “randomly” get the blue screen of death. I have Windows 8.1 and a new desktop computer for like. . .I want to say three months now. I have a feeling it could have something to do with my video processing because I’ve noticed it only happens when I’m on Firefox and opening tabs on a lot of stuff. Then again, sometimes not. It’s now frequent enough that I forgot some of the instances.

I checked my drivers through Windows and they detect nothing wrong. My updates are installed automatically. I scanned for viruses like a billion times – nothing came up. This one link suggested using Driver Reviver. It says I have a bunch of outdated drivers but I think it’s total BS because then I have to pay for them to update it. So I think (and hope) that’s all BS.

So I’m kind of at a loss on why this is occurring and how can I fix it. In no way is my computer affected at start up. This only happens while I’m already on. Then it restarts normally. I’d say that it now happens every other day I’m on, at least once. There was only one time when it happens twice in a row.
