I did a thing that shouldn't do. I had a .ROM BIOS, but I renamed a .CAP file to a .ROM file and used this for BIOS Flashback update. After that I pressed the power button. PC started but after 1 second it shutted down, and all these things happened until I plugged off the cable. After that I used ASUS' .ROM to .CAP converter, but nothing changes (if I recovered old BIOS before I doing that, maybe everything be okay). Thanks for your help advance.
