Yes, perhaps my post was very badly written. What I meant was that my nVIDIA GPU is dead and I opened my laptop to see whether there's damaged something more than GPU. On closer inspection I noticed that my nb looks suspiciously dark and I thought that it could be fried as well so I posted here to find out whether laptop would beep if nb is fried. Now I have found out that BIOS ain't gonna beep if nb is fried, but mine laptop beeps - 1 long, 2 short meaning that it is a video error, nb is fine & I should order nVIDIA replacement chip. Thanks anyway!
