Black Screen - Acer Aspire Z1 621

I have an Acer Aspire Z1 621 that i use occasionally and now it has a black screen. It starts, says 'please wait..' for about 4 seconds then a black screen. I didn't touch the registry or bios. I already tried resetting the thing. Is the hard drive or memory bad? the keyboard responds as it normally would had the computer booted normally, which is weird. Like it will be unresponsive as the computer boots, then slowly come responsive(caps, numlock). Also you can shut the computer down easily at the start, then it takes longer if the computer is on for about 20 seconds, does this mean it has booted but i can't see it?

please help.

Try accessing the bios and then press f9 to restore it and then press f10 to save and exit.

hey, i managed to fix it, just updating you now. i think my niece was at it yesterday and messed with the buttons in the back but i'm unsure. I connected my laptop with it via hdmi and messed around, held windows + p and stuff, it came on. I knew the computer was working underneath the black.

Thanks anyway, god computers are hell, lol.
