The BSOD occurs based on a malfunction on Windows PCs where either the software or the hardware prevents your system from booting or running correctly. This situation can undoubtedly arise due to the graphics card, drivers, software, or another piece of hardware within your machine. You will need to research your problem to narrow down the cause. Windows operating systems usually need to shut down after experiencing a BSOD, but the display provides an error code first (usually words). You'll need to cross-reference that error code to find out where the problem is so that you can fix it. If you have a warranty on your computer, call the manufacturer.
