CMOS Checksum Bad every boot up

Specs: Ubuntu Linux x86_64, 2.8ghz/4gb
Some reason here lately every time I boot up the computer the monitor light comes on blue " says no signal" then goes orange " standby " then I hit reset button on my tower and it will finally and stay blue like it should come on with CMOS Checksum bad F2 Setup or F1 continue using default. I assume it does not remember that it has to boot with the PCI EX card???

I checked Setup and all my settings are fine, keeps time/ date, and all other settings. This is annoying as hell having to boot it up and hit reset every time!

I built this computer about a year or more ago and really didn't use it much till my old board fried one day. Now it's my main computer.

It's an ASROCK Alive NF6-VSTA AM2 with a AMD X2 5400+ and 4GB of DDR2 Memory. Samsung SATA DVD R/W drive, 512MB PCI-ex card and 320GB Seagate SATA drive Running Ubuntu 10.04 64 bit on a 150gb partition. The other partition is a Crashed Windows Vista ! Imagine that lol.

AMD Athlon 64 3200+ @ 2.21ghz
1.5GB DDR 3200
nVidia N6600 256mb video
Segate 500 gig sata
NEC ND-3500AG DVD R/RW

Great I figured I would reset bios and put in a new bios battery now it's just a black screen with fan's spinning! I suppose the bios has crapped out on me?

Did you actually go into the BIOS settings by pressing F2. Configure it to boot from the PCIEx card and save the settings.

It is very rare for a BIOS itself to fail unless you have done something really silly. It is usually some other fault that prevents the BIOS from doing what it should.

Yes I checked it every time it said F2 to enter setup, to see if there were any changes. It was always set to boot from pci-ex, time and date always correct, boot order correct, always recognized dvd and sata drive, etc. I have even removed the card and tried to reset bios so it would boot via onboard vga but nothing. It won't even beep removing memory.

There has been no attempt to flash it at any time. Only thing that currently happens is you press the power button and fan's start spinning, cd rom makes a disc checking sound and light on it flickers, power light is on, screen goes from black to grey, Nothing else, no beeps etc.

As of nowI think the only options I can think of is replace the bios chip @ $18 or buy another motherboard like it for around $34.

It is not good just going into the BIOS and checking everything is correct, these are the default settings that will be loaded automatically. You have to make sure the settings are saved to CMOS memory when a new Checksum will be generated and saved.
