WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.
Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.
Most of the maintenance you will do in the course of your desktop PC's life is software-based: adding and removing programs or updating drivers.
But from time to time, you may need to clean the inside of your desktop computer.
Dust, carpet fibers, hair and smoke can enter the system and clog the cooling fan and other vital components.
Close all of your programs and save your work.
Click "Start" and "Shut down" to turn off your PC.
Then, unplug all of the cables and cords from the back of the tower and move the case to a flat, dry surface where you have room to work.
Press and hold the power button for 10 seconds to clear any static electrical charges from the system.
Let the computer cool off for a few minutes before opening it.
Use a screwdriver to remove the side panel of your PC, if necessary.
Different desktop systems have different ways of being opened.
Older systems those made around 2000 usually have a few captive screws on the back that hold the side panels in place.
Systems made since 2001 or 2002 are usually a lot easier to open and feature a large release button that, when pressed, allows the system to swing open like a book.
Have a close look at your desktop computer, or refer to the user manual if you aren't sure how to open it.
You don't need to remove both the left and right panel.
For low-profile systems that sit horizontally instead of vertically, remove the top panel assembly as
Identify the power supply from the inside.
You can look at the back of the computer to see where your AC power plugs in, and then just follow the part inside.
The power supply has a fan in the back and extends into your system as a large metal box. Hold the compressed air canister upright and spray compressed air around the power supply and fan, using the extended nozzle.
Use the compressed air canister to blow dust and debris out of your system, beginning at the power supply and moving toward the outer edges of the computer.
Blow the dust clear of the PC completely.
Check the side panels for built-up dust, and wipe the panels clean with a dry paper towel.
Reattach the side panels or close the PC, and reconnect it to its cables.
Check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat
Thermal compound is a sticky paste that is placed directly onto the CPU.
Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.
Hope this helps.
