Troubleshoot A Kt4 Msi Motherboard

MSI's KT4 is an ATX motherboard with support for AMD Socket A processors. The board is capable of supporting up to 6 DDR SDRAM upgrades for a total of 3GB of RAM. The motherboard also has 1 AGP slot and 6 PCI slots for maximum customization. An onboard C-Media 8738MX chip provides six-channel sound and a Broadcom 4401/5702 chip provides gigabit Ethernet. The board also has four rear USB ports and connections for two front USB ports. The KT4 uses a system of beeps to express errors for troubleshooting. The board may also be fitted with an MSI D-Bracket which connects directly to the JLED jumpers on the motherboard and uses four diagnostic lights to describe the system state.


Instructions


With D-Bracket Installed


1. Identify the four lights on the D-Bracket. The light in the upper-left corner is 1, the light in the upper-right corner is 2, the light in the lower-left corner is 3 and the light in the lower-right corner is 4. Identify the correct orientation of the bracket using the USB sticker.


2. Press the power button on your computer and monitor the lights on your computer. If none of the lights on the computer turn on, the computer is either not receiving power or the cables are not connected properly. Verify that the computer is plugged into a working outlet. Check the power switch on the back of the power supply unit (where the computer's power cable plugs into the computer) and ensure that it is in the "ON" position. If the computer still does not power on, disconnect the power cable and open the case. Ensure that the power supply unit is connected directly to the motherboard with a 20-pin power cable. Close the case and turn your computer on.


3. Monitor the lights on the D-Bracket. If none of the lights turn on, the processor is incorrectly installed or damaged. Turn off the computer, disconnect the power and open the case. Remove the heat-sink from the processor according to the instructions that came with your heat-sink. Lift the locking arm holding the processor in place. Carefully lift the processor out of its socket. Inspect the processor for broken pins and carefully reinstall it. Close the case and turn your computer on.


4. Check the lights on the D-Bracket. If light 2 remains illuminated for more than two minutes, the computer's memory is damaged or improperly installed. Turn off the computer, disconnect the power and open the case. Visually inspect each RAM module to ensure that it is snuggly fitted into its socket and the locking arms are engaged. If a module is out of place, gently push it into the socket until the arms close on it. If the module will not fit in the socket, verify that you are using DDR SDRAM. Close the case and turn your computer on.

5. Press the power button on your computer and monitor the lights on your computer. If none of the lights on the computer turn on, the computer is either not receiving power or the cables are not connected properly. Verify that the computer is plugged into a working outlet. Check the power switch on the back of the power supply unit (where the computer's power cable plugs into the computer) and ensure that it is in the "ON" position. If the computer still does not power on, disconnect the power cable and open the case. Ensure that the power supply unit is connected directly to the motherboard with a 20-pin power cable. Close the case and turn your computer on.


6. Reset BIOS to default settings if the computer will not start. Turn off the computer, unplug the power cable and open the case. Locate the nickel-shaped battery on the motherboard. Unclip the battery from the motherboard and remove it from its socket on the motherboard. Wait five minutes, then reinstall the battery, close your computer case, plug in the power and turn the computer on.


7. Download and install the KT4 BIOS (see Resources). Navigate to the install directory and rename "A6590VMS.140" to "AMIBOOT.ROM" then copy the file to a floppy disk. Insert the disk into the nonfunctional computer and turn the computer on. Hold "Ctrl" and "Home" while the computer starts. When the computer beeps four times, remove the floppy disk and restart the computer.


8. Listen for the onboard speaker as the computer starts. If you hear one long beep followed by two short beeps or eight short beeps, your video card or memory is faulty. Turn off and unplug your computer, open the case and visually inspect the memory and video card to ensure that they are completely installed. The pins on the cards should line up with the pins in the sockets and the cards should sit entirely inside of the socket. If you hear a siren sound, the CPU is overheating. Open the case and ensure that all of the case's fans are functioning properly.


9. Remove all non-essential components from your system. Turn off the power, unplug your computer and open the case. Disconnect the ribbon-style hard drive and disc drive connectors from the motherboard. Remove all non-essential PCI cards.
