Question about MSI K8MM-ILSR Motherboard

1 Answer

Want bootup says checksum bad

This is a Gateway 614GE desktop , MSI Motherboard K8MM-ILSR socket 754 AMD-Athlon 64 3400+, it worked fine for about 2 years up till about a year ago, then one day I had it on working on some data when all at once the screen went gray and started flashing garbage real fast, I turned it off waited a few minutes, turned it back on, same thing. I have done every thing I can think of including, reformatting the hard drive, reloading windows XP, inserting a new cmos battery, etc,etc, it boots-up if you play with it long enough then it goes to messing up again, HELP

When I turn it on it gets to the energy compliant screen that list all of the drives, so on & so forth, then down at the bottom theres a message that reads:
CMOS/GPNV checksum bad, what does this mean?

Then it says:
F1 to Run Setup
F2 to Load Default Values and Continue

When I press F2 it goes to MS's logo screen and just sets there.
If I press F1 it goes to reload data from so and so date.
Like I say it will finaly come up but not for long.

Is there any tests I can run?
Do I need a new Motherboard or a new CPU or both, and if so is there another or better board I can use in this machine, I would rather have Intel.

I bought another computer right after the Gateway went down, I think its still a good machine, I think it was heat that got it, no fault of the machines.

Thanks in advance for any help you can give

Re: Want bootup says checksum bad

Usually, the message you are seeing is displayed when your CMOS loses power abnormally. Even when your computer is turned off, there should always be a low-level charge from the battery, keeping track of your PC's clock, and storing information about your BIOS settings.

If the CMOS battery is dying, it will produce a weaker charge, or continuously start and stop providing power, which will trigger that message. as a result, you are losing all your BIOS settings that you are configuring each and every time, and getting that message when it happens.

It's odd that you would be getting that message when you replaced the battery, but I'd try replacing it with another one just to be sure. If it doesn't fix the problem, the motherboard may need to be replaced. In this case, the problem could lie with wireing between the casing and the chip, or even be in the chip on the circuit board itself.

You could also try flashing the motherboard, but only use that as a last resort- you could finish toasting it. Also, I can't guarantee it would fix it in the future, as all you're doing is adressing the symptoms, and forgetting about the cause.

Get a better motherboard or computer. The resolution is dependant on the graphics processor. If you can get a graphics card that will give a "widescreen" resolution then you will be able to do it by selecting it in the "Display Resolution" section of the control panel.

I am using ASUS K8VMX motherboard with AMD Athlon 64 2800+ motherboard. Now my motherboard has gone bad. I want to change it. Suggest which motherboard should i use (754 socket)

Whatever board that is in a microATX format and has a 754 socket will do - they all had the same general hardware characteristics and requirements - so get the cheapest you can find.

I can't seem to find any usefull information as to why there may be a LED flashing on the motherboard. Re-check the memory speed, and configuration, as well as the CPU that it is supported. This seems to be a fairly new motherboard, it may still be under warranty, contact MSI and request an RMA if you feel the motherboard is faulty.
