Keep on getting different BsoD errors

[Karolotopia]

The first ever bsod I got was about 2 weeks ago and that error was the critical structure corrupt error message.This morning I got another error by the name Pft list corrupt.Any idea on how to fix these errors,I’ve recently built and over locked my machine I built it over 2 months ago and I’m only getting these errors now any ideas?? Also I forgot to mention I also got the IRQL NOT LESS OR EQUAL BSOD aswell

IRQL Error often relates to drive Issues. I often have them with non working graphicscards.

First thing that would help us: What PC Specs do you have?
CPU, Ram, Mobo, GPU....
List them, please

First thing you can try is: take out the gpu and work with IGPU if your CPU does have one or try a different GPU if possible
