The issue of automatic restarts or repeated restart loops on a computer can have various causes. Here are some common reasons for this problem:

Resolving the issue of repeated automatic restarts often requires troubleshooting specific components, software, or settings. It is recommended to check the event logs, run system diagnostics, update drivers and software, scan for malware, ensure proper cooling, and seek professional assistance if needed.

The problem of repeating the automatic start while the computer is working can be caused by several factors, including:

1. Overheating: If the computer's cooling system is not functioning properly, it may overheat, causing the system to shut down and restart repeatedly.

2. Power supply issues: Power supply issues, such as a faulty power supply unit or loose power connections, can cause the computer to restart repeatedly.

3. Hardware failure: Hardware failure, such as a failing hard drive or memory module, can cause the computer to restart repeatedly.

4. Driver issues: Outdated or corrupted device drivers can cause the computer to restart repeatedly.

5. Malware or virus infection: Malware or virus infections can cause the computer to restart repeatedly, as they can interfere with system processes and cause errors.

6. System updates: Sometimes, system updates can cause the computer to restart repeatedly, especially if the update is incompatible with the system.

7. BIOS settings: Incorrect BIOS settings can cause the computer to restart repeatedly, as they can affect the system's stability and performance.

To diagnose the problem of repeating the automatic start, you can try checking the system's temperature, updating device drivers, scanning for malware or virus infections, checking BIOS settings, and running hardware diagnostic tests. In some cases, it may be necessary to replace faulty hardware components or reinstall the operating system to resolve the issue.
