Problem with Abit KR7A-RAID

[Reap]

Hello!

This is what happend:
I was going to flash the bios for a upgrad.
So I clear the COMs before I go to DOS and change the bios.
But no...
After I cleard the COMs the computer don't post at all.
I tryed to clear the COMs again same thing.(don't get any bep sounds at all)
I removed all the other hardware then the memory and the CPU and my gfx card.(memory works and GFXcard works)
Still the same problem (all 3 leds are active).
I removed ALL the memory to se if I could get a any error sound at all. (still no sound)
I removed the GFX card and tryed the same. (and still no sound, yes the speaker is connected and it works)
I have tested 3 PSU and get the same problem with all of them.
Only thing I haven't removed yet is the CPU it self. But I will try that also.

Did the board burn when I cleard the COMs?

I think my motherboard is broke.
How do I know if I have any waranty left?

Please help!

If you cleared it by changing jumper position, did you remember to put it back to the original position?

I changed the jumper as I allways do and then I put it back to its orginal possison.
