Those errors related to the hardware/ drivers problem. If you still can run the PC.
1) If you oc the cpu, ram, and reset them.
2) May try sfc /scannow in Command Prompt. Make sure the system files are fine.
3) Also chkdsk to check the HDD/SSD too.
4)May check the +3.3V, +5V, and +12V in the BIOS hardware monitor section. Just make sure the PSU works or not. And you want those voltages are within +/- 5% range. Info

5) Because you said the cpu, ram, drivers don't have problem, and if you can't find problem from the tests, then the MB may have the problem.
