bluescreen

Från wikipedia:

"The Blue Screen of Death (also known as BSoD or Blue Screen), known officially as a Stop Error [1] or a bug check, is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to crash. The term is named after the color of the screen generated by the error. In Unix-based operating systems, a similar term is kernel panic.

Stop errors are hardware or driver related, causing the computer to stop responding in order to prevent damage to the hardware or data. In the later versions of Windows (Windows NT and later) the screen presents information for diagnostic purposes that was collected as the operating system performed a bug check."

Hur man får bort dem beror ju lite på vad som orsakar blåskärmen. Det är utifrån det man får felsöka.
