The range of Socket 370 compatible central processing units (CPU) uses the Intel Pentium 3 and Celeron processors. The socket is sometimes called the PGA370 socket. You can install any speed Pentium 3 or Celeron into the socket, so upgrading a lower-end Pentium 3 to a speedy top end one is possible without changing out the motherboard. Installing a processor can be tricky if you have not worked inside your computer before.
Instructions
1. Power down your computer. Take the power cable out of the back, along with any other peripheral cables. Open your computer case with the method recommended by your computer manufacturer or computer case manufacturer. Common methods include removing screws or thumbscrews from the back of the case, opening the front panel, sliding a side panel or opening a side window.
2. Locate the CPU heatsink and fan assembly. Unplug the fan from the motherboard. Use a flat head screwdriver to unlatch the heatsink from the motherboard retention assembly. Repeat on the other side of the heatsink. Pull the heatsink off of the CPU socket.
3. Push the CPU socket handle up to a 90-degree position. Remove the current processor. Line your upgraded Celeron or Pentium 3 processor up with the socket. Insert it into the socket and lower the socket lever.
4. Spread thermal paste over the top of the processor if you are not installing a new heatsink to go along with your new processor. Put your heatsink into place over the processor, lining it up with the clips. Look for the PGA370 mark on the CPU socket. Start installing the heatsink by latching the heatsink onto the clip opposite of this mark. Use the flat head screwdriver to move the second clip into position until it latches onto the CPU retaining assembly. Plug the fan into the motherboard. Close your case and plug everything in.
