My Laptop, when i turn it on, the screen become black and even i tried to hit most of key for CMOS, still got the result.
I tried to removed RAM, clean ram slot and put it back. still not working and even i didn't put the RAM back and turn machine on but no beep sound alrert.
I don't know exaclty what is the real problem?
It's maybe mainboad problem or VGA?
I think not cause by Operating System because even i tried to hit key to go to CMOS, i still can't go the CMOS and also if the operation system, why i didnt see the message related O.S missing?
