What is the Blue Screen of Death (BSOD)?

• The blue screen of death (BSOD), also known as the stop screen or stop error, is a very annoying error that comes in second only to malware or ransomware in terms of suggesting that a user is in for a horrible day. It happens without warning, and all unsaved work is lost. And, based on what it implies, it may be the least of a user's concerns.
• BSODs are caused by driver software errors or hardware problems. A BSOD is a full system failure caused by a problem with Windows drivers and/or hardware at the kernel level. It isn't a software failure. Windows continues to execute even if the browser crashes. Because apps run at a higher level in the operating system, they are extremely rare to create a blue screen.
