Welcome to WhoCrashed (HOME EDITION) v 5.54
This program checks for drivers which have been crashing your computer. If your computer has displayed a blue (or black) screen of death, suddenly rebooted or shut down then this program might help you find the root cause of the problem and a solution.
Whenever a computer suddenly reboots without displaying any notice or blue (or black) screen of death, the first thing that is often thought about is a hardware failure. In reality, on Windows most crashes are caused by malfunctioning device drivers and kernel modules. In case of a kernel error, many computers do not show a blue or black screen unless they are configured for this. Instead these systems suddenly reboot without any notice.
This program will analyze your crash dumps with the single click of a button. It will tell you what drivers are likely to be responsible for crashing your computer. It will report a conclusion which offers suggestions on how to proceed in any situation while the analysis report will display internet links which will help you further troubleshoot any detected problems.
