The PC power supply may be the most faulty-
Items that are easy to appear in personal computers.
It heats and cools every time it is used and receives the first
AC current surges when PC is on.
Typically, a stagnant cooling fan is a predictor of power failure due to subsequent overheating components.
All devices in the PC receive DC power through the power supply.
A typical failure of the PC power supply is usually found as a burning smell before the computer is turned off.
Another problem may be the failure of the key cooling fan, which causes the components in the power supply to overheat.
Failure symptoms include a random restart or failure of Windows without obvious cause.
For any issues you suspect are a power failure, please use the documentation that comes with your computer.
If you ever remove the chassis from your PC to add adapter cards or memory, you can replace the power supply.
Make sure you remove the power cord first because the voltage is present even if your computer is turned off.
