I changed booting 1. usb (kaspersky rescue disk) 2. hard disk. After save and exit from bios i have blank or black screen. I tried remove battery and CMOS and nothing... I tried some commands like ctrl +Fn + insert/home. I tried to press F2 and nothing. I did a hard reset and also nothing... Please help me cause i dont know what to do...

i cant change to hdd as 1 because the screen is black! cant do anything... eveything is still there. I've checked the HDD and its working
 
OK try this... While the laptop is off, connect an external monitor. Turn on the external monitor and then turn on the laptop. Can you see your screens on the external monitor? If yes, Then the problem is going to be with the laptops screen. Either the ribbon cable connecting the display, the backlight, the displays inverter or the display itself.

If the screen doesn't show on the external monitor either, then it may well be the graphics card.
