A "checksum error" only means, "something is different about this startup than the last one."

It is in your bios this motherboard has been known to have isues with the bios chip.I am useing this motherboard and have been lucky I did not get this problem you are haveing.You may try flashing to the curent bios 1903 geting the download from the Asus site.

Extract
Then remove file
Rename file to P5LD2.rom
Put renamed file only on three and a half floppy disk
Reboot Holding alt F2 at same time
flash will start

If you do not feel safe doing this then you can get a new bios chip from asus with the 1903

Good Luck
Also make sure you have no air gaps on your heatsink to proc this will cause the pc to heat up and shut down.

Situation Remedies If you have encountered this error and would like to fix your computer, here are some remedies for each situation:
CMOS Battery Not Functioning Properly: If you suspect your CMOS battery is not functioning properly you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all settings are lost, you can usually get them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computers manual or tech support to remove your battery. Take down the CMOS batteries information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have remedied the problem.
Your BIOS has Been Updated (either by you or possibly a virus): If your BIOS has been updated recently, your CMOS settings may have become reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.
The Computer Was Shut Down Improperly: Sometimes when running MS Windows, if you shut down your laptop or desktop without first properly shutting down your operating system it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer before turning off the power. Usually this entails going into the Start Menu/ Turn Off Computer/ Shut Down. If you received the error, shut down the computer properly, if this is the cause of the error, the error message will not return.

ALIVEXFIRE-ESATA2 boots as far as win progress bar and blue screens. first time this happened i got an error message something like.. corrupt/bad checksum and bad cmos. ive had the pc about 3-5 years....


Bad checksum and bad cmos message signal that the chip in which the BIOS is stored has failed. This chip cannot be repaired or replaced, and since it's soldered on the motherboard it means that it is also dead.
Time for a new motherboard.

USB Over Current Status Detected, Computer will shut down in 15 seconds


this message popped up because one of the device which you connected to the usb of the pc was overdrawing current i.e more than 5V DC. Hence, the built in system security gave this message and will shut down your computer in 15 seconds. In order to avoid this message first remove all the usb items connected to it and then connect one by one and detect the faulty one and replace.

I have asus p5gc-mx motherboard when i start my pc it show some mess like,,,,,00 mass storage devices found and configured ,,,,and CMOS checksum BAD ,,,,,,,,, somebody know what is this and help me to fix...


Hi,

Checksum errors are almost always an indication of RAM problems. Have you replaced the RAM lately? Or perhaps had modules out and not reinstalled properly? Is this a new board?

No mass storage devices looks like there are problems with connections or hardware problems with your hard drive.

Are you setting up a new board or did this just happen out of the blue?

Can you get into the BIOS setup when it begins booting?

Any other information would be helpful.

Usb device over current status detected will shutdown in 15 sec


You can upgrade your motherboard's BIOS with the latest version (downloadable at: http://www.asus.com/product.aspx?P_ID=KyHOsOKWujC2QguJ&content=download). This might help resolve the problem.
If not, then the problem you are having might be because of a bug in Windows 7, since it is not yet the final version.
If possible, you can test whether this is the case or not by backing up your system & installing Windows XP or Vista, and test to see if the problem will persist or not.
