My copmuter worked fine when i powered it up.
I whachted some movie on stream and picture started to freeze
while sound worked fine. I restarted my PC and than I got
"no video input" message. I can start computer in safe mode or
in vga mode which I'm using at the moment. In safe mode I can't
change resolution to anything and while in vga mode if I try to
change resolution I get the same "no video input" message.
