Blue Screen of Death, also known as the Fatal Error, is caused when a major system process is closed or critical changes have been made to your PC’s settings. There are other reasons like mismatched system files, failure of a user-mode service, and so on.
Check Hardware Changes
Sometimes the culprit is your incompatible hardware. There’s likely to be a problem with the new hardware. Check the hardware package, specifically for compatibility with Windows version you’re currently using. If not, you might want to return it to the vendor.
See if the problem goes away after uninstalling a buggy driver, a piece of software that transmits information to hardware devices. Thankfully, Windows helps you identify such drivers. You might see a yellow color exclamation mark ahead of the device name.
