Found a pci-e s3 card I forgot I had. I tried it in the system and nothing changes.

it's a video error of some sort. The one long and 2 short is a dead giveaway.

That said, for AMI bioses a 31 code is a bit different. I never can get a 100% concrete answer on these damned 80h cards. Each version of the bios is slightly different. That said, 31 is right at the start of video testing on most versions I read. This falls perfectly into line with the L-S-S beeps.

Also, reset the bios and try a regular pci video card. As for jumpers 3&4. If I was a betting man, I would say they had something to do with the FSB selection. Considering the placement. Take them off, see what happens.

I tryed removing the jumpers and nothing changed. I did ordered a pci card to test the system.
I also have read that 31 could be a ram errors. The board calls for pc2-3200 and in using pc2-5300.

I'm just a little confused that it would pull a code that about a card missing and not something else and given that I don't deal with sk604 system that often I'd thought I asked.

I should get the pc2-3200 ram today.

Did some more looking, looks like one long and 2 short can be a ram problem with some older asus bards.

Found it out. It was the ram.
