Unusual problem when booting...

Hi, I have a Shuttle Ak-31 MB with a Athlon 1.4, 256 GB DDR, ATI Raedon Video card, cd-rom, and hard-drive. Everything was working fine until I tried to turn it on one day. It seemed to boot completely fine except for the lack of video to the monitor. Assuming it was the video card I tried swapping it with a known good one and still same problem. Tried swapping PSU, no luck, checked all connections and no luck. That is when I checked out these posts and saw the comment about the clearing the cmos and changing the cmos battery. I tried clearing the cmos with the mb jumpers and it booted fine(with all orginal parts). So I replaced the battery with a brand new one thinking I was done but still has the same problem. The only way it will boot it if I clear the cmos each time before booting. I am starting to think that something on the mb has gone out. I hope not but I am not sure what else it could be. If anyone has any suggestions I would greatly appreciate it. Thanks

(~O;?(Whenever you clear COMS, it can boot correctly?)

I'm not sure of this. Bios itself may be about to be gone for some reasons.

Try ClearCmos.exe here

If it fails, prepare Bios Update for your mobo. Take backup of it and rewrite with care.

Sorry I haven't replied sooner. I just wanted to say thanks for the help and also wanted to post my results so if anyone else has a similiar problem they can see what works. I ended up having to perform a bios update on the motherboard. Actually I ended up having to do it a couple of times, it seemed not to take the first couple of times I performed the update. (Flashed using Award's updater off their site at the Dos Prompt <not a ms-dos window>.) But it finally completed the update and actually saved it and then it seemed to work fine. I haven't had any problems with it yet. Again thanks for the help.
