|A blue screen of death or BSOD means the computer has detected a serious system level problem that it cannot resolve. Rather than continue operation and risk corrupting data it crashes with an error message. This is usually caused by hardware or driver issues or some form of malicious program, such as a virus.|
When you see a BSOD the very first thing to do is write down the error code. Without this code diagnosing the problem is just guesswork.
