The power supply is the lifeline of a system. Here are a few tips that you can use to fix power related problems on your own, without the need of a technician:-
Detect the Failed Power Supply
Ensure that everything is plugged in. There can be cases where a cord might slip out from the outlet, while you are engrossed in your work. If power is available to the monitor and other peripherals yet there is no power to your PC, then something is really wrong with your PC.
The best clue to the problem is that the PC won’t respond the moment you press the power button. If there is no sound or monitor activity, then power supply has probably ended. Though a defective switch can cause this, it may also be the outcome of a burned out power supply.
Also check the period that you will take to boot up and shutdown, as well as spontaneous rebooting. In case, the system makes quick, short beeps over a time period without booting, this might be related to power supply.
Remove a Nonfunctional PC Power Supply
It is always wise to be acquainted with ESD procedures. This needs to be done before any type of repairs work starts on your PC. Overlooking this step may cause serious damages to your computer system. The first thing you will need to do is to disconnect all external connectors.
Once you have done that, find out the power supply unit. It will be connected to all other parts of your PC. Then, unscrew the mounted screws from the case’s back that hold the power supply in its housing. Place them in a suitable location. Then, slowly take out the old power supply from it’s case. If there is lack of space in your PC, then you may have to remove a few components for this purpose.
Replace the Defective Power Supply
Most power supplies use in PC these days are of ‘’ATX’’ types. But in case you are unsure, you can take the old unit to the retail outlet and compare its width with that of an old one. Make sure that the latter is slightly longer and fits within the case. You can take the help of a salesperson for this purpose.Then, unpack your new power supply and ensure that it fits correctly. In case it has a large mounted fan, the bottom flange located at the rear may act as an impediment. Try to add it to the case where the old one was placed and utilize the mounted screws to fasten it.
Also, make it a point to ensure that no cables or unused connectors are stuck within the CPU fan or other moving parts. You will also need to do away with all external connections that are located at the back of your PC.
