@SyntaxError, thank you for this reply, but I must say, I know about those sata controller problems with the boards, that's why I have already RMAd mine and now I can't install Windows to check if everything is fine! Moreover, my BSOD is not 0x0000007B, but 0x000000CA, which I can't find nothing helpful about! I am out of ideas! I tried with only a PS2 keyboard connected - same error! Only setting under the PNP menu in BIOS is PNP System, which was NO on default. I tried it on YES - same BSOD! I wrote all the parts - all of them are necessery and nothing except the keyboard is connected so I just can't see where the PNP error is! Any other thoughts?
