So Many BSODs and some random shutdowns :/

I've just had so many BSODs and some random shutdowns. I can't be specific when some of these happen, it can be anytime. I've gotten a diversity of error codes, but mostly 0x0124. I don't know too much about computer stuff. But I have tried reinstalling windows, replaced my GPU, my RAM, and still no luck. I know 0x0124 is a very vague error, but I have gotten some other ones, so maybe you...
