Blue screens after completely upgrading my PC

[unforgivenmarramgoat]

I keep getting blue screens with various error messages after completely upgrading my PC. It now has an i7 9700k and a 3080ti. I accidentally activated Pro mode but didn't have a digital key, so I reset Windows and installed the Home version. Since then, I've been experiencing frequent blue screens with messages like "KMODE_EXCEPTION_NOT_HANDLED," "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED," and "SYSTEM_SERVICE_EXCEPTION." The "kmode" error is the most common, but none of the suggested fixes have worked. Additionally, the PC makes a slight grinding sound, though the CPU isn't overheating (I'm monitoring it). I've reseated the RAM, but it hasn't helped. please help me!
