BIOS problems

[bla2501]

hello!

i have a problem. a couple days ago i tried to update my BIOS (i have msi p67s-c43 motherboard), but something went wrong. my computer stopped working properely and i was recieving two beeps. after spending a day i managed to do the AMIBOOT.ROM trick with USB and i thought i wont have any more problems. but actually that flash did not work properely and now, i cannot do AMIBOOT.ROM flash again, and my motherboard is not responding anymore. i am not recieveing any beeps at start as i did before, even if i take RAM or other componens from the moba. but lights on moba are still turning on, when i start the computer and so do HDD, video card, .... now i do not know what to do in order to make my motherboard running well again.

thanks for your help
