简介

The motherboard is the main body of a computer. Over time, computer components degrade and may need to be replaced. Replacing the motherboard can help make a computer run more quickly, smoothly and without errors.

  1. Unplug the computer from the power supply before any maintenance or disassembly.
    • Unplug the computer from the power supply before any maintenance or disassembly.

    • Remove the two Phillips #2 head 5mm screws from the back side of the computer case. You only need to remove the screws that hold down the panel.

    • These screws can usually be removed by hand.

    • Be sure to wear an anti-static bracelet or use an anti-static mat to ensure important components are not damaged by static electricity.

    This depends on the model of system. Some systems have a lever/latch to pull to release the cover. Many Dell and HP models use latches to open the covers (no tools required to open the system). Some systems need a screwdriver to remove the screws. Some are Phillips screws, others may be Torx.

    • Make sure that you have grounded yourself so that upon removal of the graphics card you do not accidentally shock the circuit board and damage it.

  6. Press the latch on the side of the connector area to unlock the graphics card, and carefully slide the graphics card out from its slot in the computer. A good technique is to lay the computer onto it side, push the latch down and lift the graphics card out.

If you aim to replace just the motherboard, I don’t think removing the hard drive from the case should be neccessary. The point of removing SATA cable from the motherboard still stands.

Generally a good article for a beginner. Very thorough. I personally do not remove the hard drives or cpu fans as it makes it both faster and easier to hold. Disconnect all the cables and graphics card then unscrew the motherboard screws and you are good to go!

Hi, first thing I would check is video output default settings, so if you have the monitor connected to a dedicated/discreet graphics card try connecting the video cable to the mobo integrated one or viceversa. Otherwise, the fix could be as simple as replacing the BIOS battery (if the motherboard you are using as replacement is an old one) but could also be a hardware failure/compatibility issue, or a missing power cable (do you hear any beep during power-on self-test?), knowing the PC specs would help identify the problem.
