Help on Asus P4VP-MX "CMOS Checksum Bad" error

anyone please help me figure out this problem out. I have a Asus P4VP-MX mobo, 3 months ago, after reformatting my hard drive, I got a "CMOS Checksum Bad" "Press F1 to continue" "Press F2 to change BIOS settings" error upon booting. So I replaced my CMOS battery and reset my BIOS settings to default. But the error just keeps on popping out. So I ignored it. I just hit F1 every time it pops out.

And now upon booting, there's no "Press F1 to continue" "Press F2 to change BIOS settings" just the "CMOS Checksum Bad" error. I cannot go to the BIOS to update it and I cant go the Windows to perform another reformat. Please anyone tell me what to do... :cry :cry :cry

 

sounds like the mobo is bad. But just to make sure, I would disconnect anything not needed to boot (hard drive, cdrom drive(s), extra RAM, etc. ) and see if you can get past the Checksum error.

 

Reset your bios by either jumpers or removing the MB battery for a few minutes,[unplug power supply] set back to default, be sure to set time and date. ed

 

You might try another battery
The new one could be bad, sometimes they sit on the shelf long time

 

@thesmokinggun: yeah, i tried booting it without unnecessary medias but the problem stays..
@tunered: i tried resetting the bios configuration also but the error still pops.
@asus: i have three new CMOS batteries already but i cant still get pass the error..

i thanked you guys for showing concern with this problem, i think the last resort for me is to update my BIOS. Can you help me with the bootable usb thingy? i may have to boot it from my usb and update the BIOS because i dont have a floppy disk..

 

Big misconception is that just removing the CMOS battery fully resets the CMOS chip. NOT SO!

You must first remove all power from the PC. If a desktop, unplug it and if a laptop remove the main battery as well as the AC Input.
Then remove the CMOS battery for at least 20 to 30 minutes. This step is critical.

Then replace the battery and line power and reboot the PC.
Press the necessary key to enter the BIOS during boot up.
Set time and date and close using Factory Defaults.

This procedure should properly reset the CMOS.
Checksum error is usually seen when you've added more ram memory.

Good Luck,
