I've tried F12+fn and displays "F12 Boot options" with a progress bar at about 30% progress and stops, the boot-up usb is installed. 

saw that sometimes motherboard has been replaced for some issues. this laptop has had its troubles only a couple of months new, the hard drive memory needed replacing. 

please any help?
