    Default Black screen on boot

    So, I'm a complete computer buffoon seeking salvation!

    Long story short, last night when I shut down my pc everything was the usual but when I turned on my pc today after work I hit the megatrends screen, it gave me two options I cant remember, but I hit F2 which said something along the lines of continue, that led me to a screen that just kept displaying a message about boot whenever I hit space or enter, so I gave up and just powered off the machine. What I'm left with now, is after powering on it doesn't even reach the megatrends screen, everything just stays black and nothing happens. All the LEDs are on, the fans are whirring away all happy like, but theres just nothing otherwise, no signal, no megatrends screen, and nothing when I hit the f-keys or delete etc.

    What I have done so far is take out the cmos battery to see if that resets the bios (which I know nothing about, just took a stab in the dark) and yeah, that's about it.

    Despair grips me.

    Are you using Win 10?

    Most Monitors have a power LED, when the Computer is off it may be one colour or not glowing but when on turns to another. If it doesn't change colour then its not getting the signal.

    The fact its not getting the BIOS options or Name (Megatrends) then its highly unlikely the Operating system as it hasn't even got to that sequence of loading the OS yet.

    Do you have a graphic card or onboard Graphics ?

    I have a graphics card, I think its GIGABYTE GEFORCE GTX 1660 super. Yeah I'm not getting a signal, tried turning the screen on and off but it just says "no signal"

    Check that you haven't bent pins on the computer screen/monitor plug when you put it back into the computer box, make sure you are plugged into the correct socket for the graphics card and not the onboard graphics socket.

    You need to make sure everything is plugged into the correct places in the correct way. If fans are running and led's are on on the computer box then perhaps it's the connection between the computer and the screen is in some way faulty.

    Are there any sounds from the speakers you presumably have connected?

    Do you have a spare screen to connect and check instead of the one you have been using?

    Have two screens but neither of them are working, both are getting no signal. One thing I have done recently is change the resolution so my desktop spanned to both screens. I have seen the BIOS megatrends screen once, that was when I clicked F2 (which said continue) and then restarted my pc, its since then that I don't even reach the BIOS screen anymore, there's just nothing, like I've made the wrong choice and died Haha.

    As mentioned earlier "highly unlikely the Operating system as it hasn't even got to that sequence of loading the OS yet." And the resolution wont have had a chance to load yet.

    If the motherboard has onboard Graphics, remove the Graphic card and plug one monitor directly into the board, turn on, if still no graphics could be a failed Motherboard OR even a dead CMOS battery, change it, they are cheap enough and can get them from any place that has a battery stand. "IF" the battery has died then a common effect is the BIOS wont load and computer wont display.

    Because you got a BIOS prompt and it all turned to custard its usually hardware related somewhere. The reply/ Statement "both are getting no signal" says it all really.

    No signal means the monitor can';t see the card.
    As Wainuitech says here - hardware issue. The initial thng tells me it's probably something to do with the motherboard.

    Have you tried putting in a brand new BIOS battery?

    Your original problem about pressing F2 could have been a warning about corrupt settings from a flat battery.

    But some motherboards won't boot with a flat or missing battery, only a good one.
