WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.
Unplug all electronic cords connected to the computer.
At no time during the installation should any cords be connected to the computer.
Remove the screws holding the computer cover case, and remove the cover case.
Locate the computer power supply box, which looks like a large box out of which a bundle of wires run and connects to the power cord jack on the outside of the computer case.
Unplug the power cables from the internal devices connected to it.
Be careful not to damage any of the sensitive control boards or devices inside the computer, and be certain to remember--write it down if you need to--what devices will need reconnecting to the new power supply when you finish the installation.
Unscrew the power supply from the inside of the computer case and remove it. Check the original power supply's red voltage switch for the correct setting.
It should read 120 or 240 if you live within the United States.
Confirm this setting as the correct voltage setting for your power outlets.
Make sure your new power supply gets set to the correct voltage setting before you install it.
If it cannot be set to the correct voltage, do not proceed with the installation or you may damage your computer.
Return the new power supply and buy one that is compatible with the voltage requirements.
Install the new power supply, reattach the screws that will hold it in the proper place inside the computer.
Reattach the power cables that come from the new power supply to the devices that were connected to the old power supply.
Make sure all of these connections are firmly in place before you turn the computer back on.
Reattach the computer power cables and all the cords connected to the computer during normal operation, but do not close the computer case yet.
Keep your hands clear of the inside of the computer case as you attach power cords and peripheral devices.
Turn the computer on and observe the performance of the computer without touching anything inside.
Do all the computer fans function normally?
Does the computer operate as well as or better than before?
If you feel that the computer behaves normally and you do not encounter any problems, turn the computer off, remove all the power cords and peripheral cables once more, and close the computer case.
Then reattach the power cords and peripheral cables and begin using the computer.
Check for errors if you encountered any problems starting the computer or if it would not start at all, unplug all the power cords and computer cables connected to the computer and look inside.
Make sure that you connected all the correct power cables inside the computer securely and did not miss any.
If you have confirmed this and the computer still doesn't start or operate normally, call your computer manufacturer or a professional computer repair shop for assistance completing the installation
hope this helps

Double click on the "Smart Cover" icon on the desktop. Enter in the Smart Cover lock code if you have set one up and click on "Unlock" to disengage the hardware lock that prevents the case panel from being opened.
Click on the "Start" button at the bottom toolbar of the desktop and choose "Shut Down." Unplug all of the cables from the back of the computer once it has finished powering down.
Set the Compaq computer case on its side and remove the two screws connected to the top and bottom ends of the case panel. Slide the panel to the left and pull it directly off the case.
Disconnect the SATA cables running from the power supply, drive bays and processor fan to the motherboard. Remove the screws holding any expansion cards you may have previously installed into the AGP ports on the lower right side of the motherboard and then pull the cards out.
Pull back the clamp holding the processor fan on. Pull the fan and then the processor off of the motherboard. Pull off the RAM modules from the motherboard.
Remove the screws holding the motherboard into place and pull the entire motherboard directly out of the case. Check the orientation of the replacement motherboard and make sure the USB ports and AGP expansion card slots are facing towards the back of the case. Lay the new motherboard down into the case onto the mounting screws sticking out of the bottom panel.
Place the processor back into its socket on the motherboard and connect the fan on top. Snap back on the fan clamp. Place the RAM modules back into their slots. Re-connect all of the SATA cables to the drive bays and power supply.
Set the side panel back onto the case and re-connect the case screws. Connect all of the cables into the back of the case and power the computer back on. Wait for the operating system to load to make sure the motherboard is working properly.
Navigate back to the Smart Cover program, enter in the password, and press the "Lock" button.

You will notice that replacing the fan is not specifically
mentioned, but it should be fairly easy.
Open the case as noted in the instructions, follow the power
wire from the fan to the motherboard, then unplug the connector from the
motherboard, and remove the assembly.
Some of the earlier fan shrouds just lift up and out, but
others have tabs to hold them in.
Regarding the fan, there might be two release levers
accessible from inside the case, but the one by the PSU can be hard to
It might easier to push the retaining tabs, in from outside,
using a small screwdriver, pen or whatever.
The installation of the new fan, is just a matter of fixing
the new one in place and connecting the cable.
Good luck, and do rate the solution if got help
