Upgrade a Dell 8300 Motherboard
A primary reason you would upgrade the Dell 8300 motherboard is for updating the CPU (central processing unit). You can, however, replace the motherboard to upgrade available connectors, such as more USB or Firewire ports. Regardless, the CPU and motherboard must be compatible. Dell designs their motherboards in a very specific way, so make sure to verify that the new motherboard will fit and can be secured inside the computer case.
Instructions
1. Unplug the Dell 8300, then lay the computer on its right side.
2. Press the release buttons on the top and bottom panels of the computer, toward the back. Rotate the left panel up to open the computer.
3. Disconnect the power and data cables connected to the motherboard.
4. Pull up on the tab located on the side of the motherboard closest to the front of the computer, then slide the motherboard toward the front of the computer. Lift it up to remove it.
5. Push clips holding the RAM modules on the old motherboard apart from each other, then insert the RAM into the RAM slots on the new motherboard. Push down firmly until it clips into place.
6. Un-clip the heatsink assembly from the old motherboard, then un-clip the CPU and lift it out of the socket. If you are using a new CPU, skip this step.
7. Place the CPU on the socket of the new motherboard. Lower the lever on the right side of the socket and clip it into place.
8. Place a small amount of thermal grease on the CPU, then place the heatsink assembly on top of the CPU and clip it into place.
9. Place the motherboard into the Dell 8300 case and slide it towards the back until it clips into place.
10. Reconnect the power and data cables to the motherboard and close the computer case.
