Pavillion DV6 Black Screen

[yura910721]

My laptop gets stuck on black screen when I try to boot it. It would occasionally boot to straight to windows without showing BIOS screen or any loading screen whatsoever, something like 1 our of 50 attempts. So I saw numerous suggestions online and no, conclusion isn't that video card is fried(because it occasionally would load OS and I tried with external monitor connected as well) or RAM isn't properly attached(I tried removing it and putting it back in). I tried pressing all sorts of key combos that were given on HP support website, no luck. If it sometimes loads OS directly, doesn't it mean that motherboard isn't faulty? I am running out of ideas. One catch though: CMOS battery holder broke, so battery isn't quite properly attached and I tried replacing one as well. Is it possible that CMOS battery can cause BIOS to fail to load? Please if anyone has any suggestion, I would love to hear it.

Thank you for the response. Unfortunately, I got stuck on #2: I tried pressing F10 repeatedly, but nothing appeared on the screen and all I've got is a beeping sound(I think usually you'd get something like when you press the key too often or something). When boot the laptop up, it sounds like laptop is doing some work, fans are spinning. But I cannot see what is going on. 

I did try to connect laptop to the external display via VGA port, but nothing appears on the screen. I have a feeling that laptop's internal display is functional, it is just BIOS menu doesn't appear. I don't even see HP logo on the loading screen. All I see is a black screen.
