The Computer Fails to Start or There is No Video



If you experience a situation in which the computer does not start at all or if it does turn on (lights turn on and fans are spinning), but the computer does not show any image, listen for a series of beeps during start-up.

  • When beeping codes are heard, refer to (Table 1) to help troubleshoot the issue with your computer.


    Repetitive Beep Codes
    1

    Possible motherboard failure - BIOS ROM checksum failure.

    2

    No RAM detected.
    NOTE: If you installed or replaced the memory module, ensure that the memory module is seated properly.

    3

    Possible motherboard failure - Chipset error.

    4

    RAM read/write failure.

    5

    Real Time Clock failure.

    6

    Video card or chip failure.

    7

    Processor failure.

    Table 1: Repetitive Beep Codes



  • When no beeping codes are heard, perform the following steps:
    1. Disconnect all external peripherals except the keyboard, mouse, and monitor (for desktop systems). Peripherals also include external storage devices such as flash drives, USB devices, cards etc.
    2. Drain MB power about one minute (until MB lights turn off, which can take from 20 seconds up to one minute).
    3. Make sure that the monitor is receiving power and that it plugged into the correct port on the video card. For SLI systems, the correct DVI port to be used would be the one on the primary (upper) video card, the one to the left looking from the back of the computer. This port can also be used for single card configurations.
    4. Remove all the memory sticks (found next to the CPU) and attempt to POST the system using one memory stick at a time on Slot 1. Reinsert all memory sticks, and make sure that their connection to the motherboard is optimal. If after doing this the problem reappears then you may have a defective memory slot on the motherboard.
      Note:
