Hi,sorry for my English. I bought anew asus n750jk. It came with no os. I put a DVD with windos 8. Entered a bios mode. And boot order was 1. Sandisk ssd 2. Machita DVD 3. Cd/DVD. I put a cd/dvd in the first place,then went to f10 button,save. Laptop resets itself and after that,completely dead,black screen,no boot, nothing. Went to dealer,they gave me the another new laptop. Same thing happens. Any solutions? Thanks!
