The Blue Screen of Death (BSOD) with a Sad Face

I've been experiencing the Blue Screen of Death (BSOD) with a sad face on my Windows PC, and it usually happens unexpectedly while I'm working, browsing the internet, or running applications. The computer sometimes restarts automatically, and I'm not sure whether the problem is caused by outdated drivers, hardware issues, corrupted system files, or a recent Windows update, so I'd appreciate any advice on how to identify the root cause and prevent these crashes from happening again.
