Hi, i have this problem: when i would to enter in the BIOS settings (DEL) or i would to set the BOOT (F7) the monitor remains black, like dont have video signal.
If i dont push any keys, the boot work perfectly and the Windows page appair.
Please try to clear the CMOS.
Please turn off the PC , unplug the power supply, and press the CMOS button (put the pin in the pinhole and press it ) for about 10 seconds , restart the PC after ten minutes.
