Hi @RAKESH2708,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your PC!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Check Power Source:

• Ensure that the power cord is securely connected to both the desktop and the power outlet.
• Try plugging the desktop into a different power outlet to rule out issues with the outlet.

Power Supply Check:

• Make sure that there are no visible signs of damage to the power supply unit (PSU).
• If you suspect the PSU is faulty, consider testing it with a multimeter or by replacing it with a known good unit.

Perform a Hard Reset:

• Disconnect all peripheral devices and remove the power cord from the desktop.
• Press and hold the power button for about 15 seconds to drain any residual power.
• Reconnect the power cord and try to power on the desktop again.

Check for Loose Components:

• Open the case and ensure that all internal components (RAM, CPU, GPU, and storage drives) are securely seated.
• Check for any loose cables or connections inside the desktop.

Remove and Reinstall RAM:

• Sometimes, reseating the RAM can resolve power issues.
• Remove the RAM modules, clean the contacts with a soft brush, and reinstall them firmly.

Test with Minimal Configuration:

• Disconnect all non-essential components, such as additional drives, external devices, and any expansion cards.
• Try starting the desktop with only the essential components (CPU, one stick of RAM, and the power supply).

Check for Overheating:

• Ensure that the cooling system (fans and heatsinks) is working properly and that there is no dust accumulation blocking airflow.
• Check the thermal paste between the CPU and the cooler and reapply if necessary.

CMOS Battery:

• A failed CMOS battery can sometimes cause power issues.
• Replace the CMOS battery on the motherboard and reset the BIOS to default settings.

I hope this helps.
