When I press F10 or F9, there is no option to boot from DVD or USB. I tried using both. When I go into BIOS, it is froze with a continous keee sound.
Open bottom panel, remove RAM, wipe it a bit (dry cloth) & reinsert it, then try again.
If it works, good, otherwise visit some service center.
The keyboard is not working as well. I am using USB keyboard. Looks like this one will end up at a service center.
PS : Currently installed Ubuntu works fine with an external keyboard.
then I guess its problem with boot cd or usb
