The Dell Dimension 8300 from Dell Computers was designed to be a high-end consumer PC, using the then-top-of-the-line Pentium 4 processor. In the years since its introduction to the marketplace, there have been many advances in CPU technology, which now renders the Dell 8300 obsolete. If you are looking to upgrade the Dell 8300 to the Intel i7 CPU, know that you will have to completely swap out the old motherboard, as the Pentium 4 and i7 are built for completely different socket types.

  1. 1

    Power down your PC and disconnect the power cable leading into the rear of the machine. This is strictly for safety reasons.

  2. 2

    Open your Dell 8300 tower by sliding the side panel to the rear until it pops loose from the rest of the tower. Once loose, simply lift away and place to the side to gain access to the interior of the tower.

  3. 3

    Lay the tower on its side and locate the screws holding the motherboard in place. Take this time to also disconnect any cables leading in to your motherboard, as well as removing any expansion cards (video cards, sound cards) that you will want to use in the new motherboard.

  4. 4

    Remove the screws holding the motherboard in place.

  5. 5

    Lift the old motherboard out of the computer and place to the side. Now slowly insert the new motherboard into the tower, making sure the screw holes align with the spacers on which the old board rested.

  6. 6

    Secure the new motherboard in place with the new screws.

  7. 7

    Reconnect the cables and any expansion cards to the new board. The new board will have identical plugs and slots as the old board, making the process easy.

  8. 8

    Close your computer tower and reconnect the power cable to complete the process.
