I was merely explaining what they should do, in conjunction with my last sentence.
It would appear that you have a Hardware problem.
And if pressing F2 does not put you into BIOS, otherwise called Setup, that problem is with the Motherboard and/or the Keyboard not working.
One thing, make sure that you have no USB devices plugged in when trying to Boot.
If not under Warranty and problem continues, I suggest that you take it to a local and reputable computer repair Shop.
Cheers.
