What is more strange, Palit itself says nothing about system requirements either on the site or in their instructions.
In another forum I was advised to clean bios. It halfly worked. I saw another screen after HP logos - it was a message saying something like "bios default settings loaded". This screen is shown for a second after each cleaning and then the system hangs again.
I thing that if I find a way to prevent default settins loading (in a month or so) I shall be a bit closer to the solution.
