Windows Vista Shutdown Problems - Why Your System Isn't Working and What You Can Do About It

Both hardware and software issues can cause Windows Vista to restart or shut down unexpectedly. Often, these sudden shutdowns come with a blue screen of death, also known as a stop screen or BSOD. Stop screens appear whenever a critical error has occurred and are meant to inform the user that Windows Vista can no longer operate due to the error.

While holding the can upright, simply spray the compressed air in between the vents to remove the dust and debris clogging the computer fan.
