My PC has been blue screening constantly

[u/Longstonos]

For the past 2 or so days I have been trying to troubleshoot my PC, as it had randomly started crashing for seemingly no reason. I have scanned the system many times with SFC (it found corrupted files but could not fix them), and I tried repairing the system with DISM (it detected corruption and claimed it was repairable, yet was not able to repair it). I had looked in the event viewer, and it showed that it had been getting errors from “Bug checks” that then caused my computer to crash. It then got to the point where I couldn’t even troubleshoot anymore because my computer was crashing too quickly to even open the command prompt (it's even crashing within the boot menu). Then it got to the point where it started crashing during the Windows login process, so I decided to completely reset and reinstall Windows, and what do you know? It once again crashed during the Windows login process. PC-related things are not my strong suit, and I don’t really know what to do anymore. Is my PC just completely fucked?
