- Common symptoms
- BSOD
When Microsoft Windows encounters a condition that compromises safe system operation, the system halts. This condition is called a bug check. It is also commonly referred to as a system crash, a kernel error, a Stop error, or BSOD. A hardware device, its driver, or related software might have caused this error.

- Safe mode
Safe mode is a diagnostic mode of a computer operating system, using only default settings (VGA monitor, Microsoft mouse driver, no network connections, and the minimum device drivers required to start Windows). If a symptom does not reappear when you start in safe mode, you can eliminate the default settings and minimum device drivers as possible causes. Windows automatically initiates Safe Mode if it detects a system boot failure or registry corruption. Safe mode can be accessed manually by pressing the F8 key as the operating system boots.
