When your Windows operating system experiences an unrecoverable error, the operating system will usually crash leading to a blue screen similar to the image below:
A blue screen is usually accompanied by information detailing the crash. System crashes can have several causes including:
- Failing hardware
- Faulty software
- Incorrect system memory timings
Unfortunately blue screen error messages do not provide sufficient information to diagnose the cause of a PC reboot/crash. If you are experiencing repeated system crashes that lead to a blue screen, you may be asked to provide a complete memory dump file to help our engineering team investigate your issue. By default, Windows will save a PC crash log as a small memory dump file which also does not include sufficient information for our team to debug. You will need to change your system settings to save a complete memory dump file.
Capturing a Windows bug check complete memory dump file.
