Random and unprompted system reboots can be caused by various issues. Here are some common causes and troubleshooting steps:
1. Hardware Issues:
- Overheating: Ensure your system is well-ventilated and dust-free. Use a temperature monitoring tool to check CPU and GPU temps.
- Power Supply Problems: A faulty PSU can cause sudden shutdowns. Consider testing with another PSU.
- RAM Issues: Run a memory diagnostic tool like Memtest86.
2. Software Problems:
- Driver Issues: Update all drivers, especially for the GPU and motherboard.
- Malware or Viruses: Run a full system antivirus and malware scan.
- Operating System Errors: Run system diagnostics like SFC (
sfc /scannow) or DISM on Windows.
3. System Settings and BIOS:
- Power Settings: Check advanced power settings and disable automatic restarts after system failure.
- BIOS Settings: Reset BIOS to default settings or update it to the latest version.
4. External Devices:
- Disconnect external devices to rule out peripheral-related issues.
