Hi @Likithroshan,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your system is experiencing sudden blackouts, shutting down, and restarting unexpectedly, this can be caused by a range of issues, including hardware failures, software problems, or system overheating. Here's a comprehensive guide to diagnose and fix the issue:

1. Check for Overheating

Monitor Temperature:

• Use software tools like HWMonitor, Core Temp, or SpeedFan to check your system’s temperatures. Overheating can cause the system to shut down to prevent damage.

Clean Vents and Fans:

• Ensure your computer’s vents and fans are clean and unobstructed. Dust buildup can cause overheating.

Improve Airflow:

• Make sure your computer is in a well-ventilated area. Consider adding or adjusting fans to improve airflow.

2. Inspect Power Supply

Check Power Cables:

• Ensure all power cables are securely connected to your computer and power outlet.

Test with a Different Power Outlet:

• Plug your computer into a different power outlet to rule out issues with the current outlet.

Test Power Supply Unit (PSU):

• If you’re comfortable working inside your computer, check the power supply unit (PSU) for signs of failure. Consider replacing it if you suspect it's faulty.

3. Run Hardware Diagnostics

Run Built-in Diagnostics:

• Many systems have built-in diagnostic tools. For example, Dell computers have built-in diagnostics accessible during startup.

Use Third-Party Tools:

• Use third-party diagnostic tools like MemTest86 for memory testing or CrystalDiskInfo for hard drive health.

4. Check for Software Issues

Update Drivers:

• Ensure all drivers, especially for graphics cards and chipset, are up to date. Visit the manufacturer's website to download the latest drivers.

Check for Software Conflicts:

• Review recently installed software or updates that might be causing conflicts. Try uninstalling recent software to see if the issue resolves.

Scan for Malware:

• Use a reputable antivirus or anti-malware tool to scan your system for malicious software that could cause instability.

I hope this helps.

Take care and have a good day.
