BIOS ROM Checksum Error - no POST, no beeps, no display -HELP!

ASUS P5LP-LE OEM motherboard in an HP Pavilion Media Center TV m7357c Desktop PC ( is giving a BIOS ROM Checksum Error. Won't POST, won't beep and usually no display. I've only occasionally been shown the error mentioned, usually no display at all. Probably need to reflash the BIOS but how can I do that if it won't boot? This PC doesn't have a floppy drive either although I could probably get my hands on one but how do I get to the BIOS for it to recognize it? I've tried removing all cards except video, swapping ddr2 sticks and slots, removing and replacing battery. Is there a solution for this problem or do I just throw away my mobo?

There isn't much you can do. First thing you want to try is shorting the cmos. You can do this via the jumper or just carefully remove the power from the computer and then remove the on-board motherboard battery. Just let the computer sit for 5 minutes, replace, and try again. If it's no go then you can get an RMA for the board. Most companies will replace them for Free if it's not super old.

If your computer turns on and no display then you have faulty memory cards, replace them with new ones and make sure you use the right kind. Bios settings are usually set to default and factory settings, you should not have to update them. Usually if you hear no beeps when you turn on the computer, then your memory cards are faulty. I hope this helps.

Wiring diagraM for hp a6120n

product specs are here
motherboard is
  • Motherboard Name: [Asus] P5LP-LE
  • HP/Compaq motherboard name: Leonite2-GL8E
    HP motherboards specs:
    You might try here for a manual which might tell you what you need to know.
    BUT this is the one. Apart from much other useful information it contains mainboard pin-out information for connection to the case (I think these are pretty standard anyway)

    (The trouble is this is a motherboard made by Asus for HP. As such Asus do not provide any information about it whatsoever. HP information if you can find it is not sufficiently detailed)

    P5LP-LE Bios beep codes

    The beep codes are BIOS specific and so you will need to pay attention to the post as your computer boots and note what BIOS it has. Then you can go to a website such as and look up the codes for your specific installation. On the right hand side you can select different types of BIOS.

    No display problem for intel D865GSA board

    What are you formatting ? Have you changed the RAM. Does tour system work in its original configuration ? You do not say what the pattern of the beeps is. Before the display disappears, is there a message sent to the screen ?
    From the manual

    Whenever a recoverable error occurs during POST, the BIOS displays an error message

    describing the problem (see Table 53). The BIOS also issues a beep code (one long

    tone followed by two short tones) during POST if the video configuration fails (a faulty

    video card or no card installed) or if an external ROM module does not properly

    checksum to zero.

    An external ROM module (for example, a video BIOS) can also issue audible errors,

    usually consisting of one long tone followed by a series of short tones. For more

    information on the beep codes issued, check the documentation for that external


    There are several POST routines that issue a POST terminal error and shut down the

    system if they fail. Before shutting down the system, the terminal-error handler issues

    a beep code signifying the test point error, writes the error to I/O port 80h, attempts

    to initialize the video and writes the error in the upper left corner of the screen (using

    both monochrome and color adapters).

    If POST completes normally, the BIOS issues one short beep before passing control to
    the operating system.

    I have an HP Media Center PCm7360n that does not seem to boot up. Upon startup I get a black screen, no "beeping" sound and fans stay in high speed. Could this be a motherboard problem?

    yes i had one ...same the side of the PC (WITH POWER OFF) make sure the SATA lead is secure to the hard drive...i know it sounds dumb but my HP PAV Media Centre did the same thing, and that was the prob, the SATA Cable and DATA RIBBON moved a fraction even though it was connected it wasn't reading the DRIVE....try that.

    The coin battery on the motherboard is drained. That will cause it not to boot. Replace the battery and reset the time and date and you're good to go.

    HP Compaq 6005 Pro, nine beeps

    9 BeepsNine beeps means that there has been an AMIBIOS ROM checksum error. Literally, this would indicate an issue with the BIOS chip on the motherboard. However, since replacing a BIOS chip is sometimes impossible, this AMI BIOS issue is usually corrected by replacing the motherboard.
    Use utility tool like RegInOut to repair corrupt registry files and keep your computer safe from being damaged.

    I have a gateway desktop that is beeping before post. It beeps and will not post.

    It depends on the motherboard model, but here is an example of the error codes for a gateway:
    Beeps Error Message Description 1 Refresh Failure The memory refresh circuitry on the motherboard is faulty. 2 ECC Error Error Checking and Correction (ECC) is supported on this product. 3 Base 64 KB Memory Failure Memory Failure in the first 64 kilobytes (KB). 4 Timer Not Operational Memory Failure in the first 64 KB, or Timer 1 on the motherboard is not functioning. 5 Processor Error Ther processor on the motherboard generated an error. 6 8042 - Gate A20 Failure The keyboard controller, 8042, may be bad. The basic input/output system (BIOS) cannot switch to protected mode. 7 Processor Exception Interrupt Error The processor generated an exception interrupt. 8 Display Memory Read/Write Error The computer video adapter is either missing or its memory is faulty. This is not a fatal error. 9 ROM Checksum Error Read-only memory (ROM) checksum value does not match the value encoded in BIOS. 10 CMOS Shutdown Register Rd/Wrt Error The shutdown register for complementary metal-oxide semiconductor (CMOS) random access memory (RAM) failed.

    Continuous beeping sound

    Do you get video? If so then it could be a stuck key on the keyboard.

    Do you get no video? If so then reseat the RAM.
