Blue screen crashes indicate a critical system error has occurred. These will only happen on Windows systems, and sometimes indicate a corrupted operating system or failing hardware.
  1. Update your drivers and operating system to resolve any compatibility errors.
  2. Check your system for potentially unwanted programs and malware with a security scan.
  3. Security programs can prevent your drivers or hardware from being accessed correctly. Troubleshoot your security programs.
  4. Use System File Checker to scan your operating system files for errors.
  5. Overclocked hardware can cause system instability. Disable any active overclocking on your hardware, including factory overclocking.
  6. Overheating hardware can cause Windows to crash. Check for overheating components.
  7. Improperly slotted or failing Memory can cause system crashes. Scan your RAM for errors.
  8. Consult your computer manufacturer or a local technical troubleshooter for further assistance. Blizzard Customer Service cannot assist with this issue as it is not caused by a Blizzard product.
