A memory dump is what happens when Windows crashes. The memory is dumped into the pagefile and saved for the next reboot. Once Windows reboots, it reclaims the memory dump data from the pagefile and saves it to a file, which usually ends with the .dmp extension. Analyzing these dump files can help to figure out what's causing your system to crash. While they don't offer a "sure" fix, they provide clues to the cause of a crash so that we can work on fixing them. In my experience most system crashes are caused by faulty/corrupted drivers, malware, or hardware failures (in that order). Following the steps below will help us determine what may be causing your computer to Blue Screen, or crash.
