so, by mobo got burnt and i initially thought it was the case. i got a replacement from gigabyte (nice people...sympathised with my plight) and i assembled it outside, but it still burnt. however i managed to shut it off quickly and thus, the damage wasen't very extensive and i was able to repeair the mobo myself. i started the mobo again with only the cpu and ram installed (smps was fine, id checked it with another computer) and the beep came from the speaker. then i installed the gpu again and it burns. also, should i ask powercolor, not only for a replace ment but for compensation (its a new build) ??
