Often, there are situations when the computer's power supply stops working, because of which the computer cannot be turned on, or it spontaneously turns off at regular intervals. What to do in such a situation?
Instructions
Step 1
Power off the computer and remove all cables and cords connected to the chassis. Unfold the system unit with the back towards you.
Step 2
Remove the two screws on the back of the PC system unit. Grasp the metal tab on the top of the case with your fingers. Lift it up to unlock the side panel of the computer system unit.
Step 3
Click on the panel and slide it from right to left. Remove the screws holding the power supply in place in the upper left corner of the motherboard. Disconnect the cables from the power supply to other hardware.
Step 4
Make sure the power supply does not give off a burning smell. Stop your actions immediately if you feel it - in this case, the computer must be urgently shown to a specialist from the service center.
Step 5
Check if the power supply fan is clogged with dust. Use an empty spray can to clean the blades. Replace the power supply and reconnect it. Build your computer and see if the problem is fixed or not.
Step 6
Remove the power supply from the chassis again if the problem persists. Check the model number on one side of the unit. Visit the manufacturer's Web site to see how you can troubleshoot possible issues.
Step 7
Get a new power supply if you can't fix the problem. Often the breakdown of this device can occur due to insufficient power and overloading of the internal components of the computer. Read the instructions for all components, find out what is the optimal power for them, and select the appropriate power supply.
Step 8
Make sure the electrical outlet you are connecting the computer to is working and supplying sufficient voltage. Any, even the most insignificant, short circuits often lead to the failure of any power supply.
