Video drivers, in my experience, can produce all kinds of strange errors.
If you can boot up in ‘Safe Mode’ try uninstalling the video driver and let it re-boot to Microsft’s generic driver and work from there.
Yes would agree that a heat issue would still occur in ‘safe mode’ but….you never know.
There are many causes of boot errors. Corruption, failing drive, etc. Is it still not booting in ‘Safe Mode’?
Can you make a USB boot drive with Windows installation and attempt the boot repairs?
Let us know how it goes.
