Aloha, my name is Andy. In this video I will upgrade the CPU for the HP Compaq dx2400 Microtower PC. For this operation I need: a flat screwdriver, thermal paste, Isopropyl alcohol to clean the CPU and the heatsink, paper towel to clean the CPU and the heat sink, and the new CPU.
So lets begin. I already removed the side cover. Now I will remove the monitor cable. And the power cable. And now I press the power button for about 10 seconds to discharge the capacitors. Ok, now I will remove the heatsink from the CPU.
The heatsink has 4 screws. I will use my flat screwdriver. I unscrew the screws in diagonal. I speed up the video, because it taking a long time to unscrew the 4 screws. Ok, I almost removed the heatsink.
Finally I removed the heatsink, and you can see the thermal paste on the heatsink and CPU. Now I will clean the CPU from the thermal paste. First I wipe with a dry paper towel. I wipe the heatsink too.
And now I will wipe with isopropyl alcohol. Now I remove the old CPU from the socket. Intel Core 2 DUO E7500 @ 2.93GHz The upgrade CPU is a Core 2 DUO E8400 @ 3.00 GHz. The gold triangle has to be aligned with the socket triangle.
Now I insert the CPU in the socket. After I locked the CPU in the socket I will clean again with isopropyl. And now I put back the heatsink. And now I will screw in the 4 screws. Now I plug the monitor cable and the power cable.
And now I start up the PC. The Windows recognize the new hardware and I must restart the PC to apply these changes. The Windows recognized the new CPU. And now I will run the Windows Experience Index.
