my pc beeps 1long 3 short with the following config:
board: asus m2n32 ws pro
graphic: asus hd 6870

According to beep code tables, there should be a problem with the graphic card or its memory...

I had such a problem before, which - after i failed in testing and diagnosing - i solved by putting the card in my second pcie slot.
today i needed to unplug the card. when i returned it to the 2nd slot it, i got beeeep beepbeepbeep.
the strange thing is that the card works fine in other pcs and my pc works fine with other graphic cards.
i tested ram, too. power is plugged in. i "removed" the dust from the board.tested the other pcie slot.
and have no idea left

got any hints, advices?
