No video, or boot

[lopertommy]

Asus g74sx downloaded updates from asus webpage. Just bought it. Factory rest it. Instal vga driver. Need to reboot to install new one. Reboot it says installing 120 if 155 files reboot now? Yes. Turns off comes back on stuck in boot loop. Enter bios configure boot from optic drive shuts downs comes back up flickers goes to black screen. Power button lights up fans run dvd runs gets warm. No boot screen just black. Tried everything found in forums. CMOS external monitor rams all the button presses no change. I believe video drive was deleted somehow boot configure got lost so no way to boot to reinstall video driver. No video driver to see how to reboot. Anybody got any ideas?

You can try the factory restore F9 option, if it shows up when you first turn it on.
