Answer 1

And I would say that the answer is Dexp , but most likely it's still troubles with the settings.
In general, the standard check in this case will be booting from a Live-CD - if it's ok there, then most likely everything is ok with the computer. In BIOS, by the way, the same hat? It's also an indicator ...
If it's under warranty and it's broken - hand over this junk and take the money back.
