New Acer V3-772g booting to a blank screen?

I recieved a new Acer V3-772g-5413 about a week ago. Booted up fine the first time I started it. 2nd time I go to start it, it gets past the Acer logo (Bios screen?) and then the screen turns blank (Bright white, the screen was clearly powered). I've found that rapidly hitting F12 throughout the bios screen will sometimes allow it to boot normally. If that doesn't work, I use F2 to get to the bios menu, and then exit and save without actually changing anything. This will be followed by a succesful startup. Not sure why.

So two questions:

What does F12 do on this model, and why does that allow me to boot normally?

Any suggestions as to what the underlying problem might be?

After the first startup I installed a bunch of programs, drivers, etc., so probably one of those is at fault? How should I test that?

I've turned off the fast boot option in the bios, but no luck.

Thanks in advance!

Maybe if one of the programs you installed is the problem, then it would probably be one from an unreliable source (like free, "virus-free", download of something you're supposed to pay for, or something like that).

So I've methodically uninstalled every program that I added before this problem began, no luck. I don't think I had any programs from an unreliable source. I've also gone through and disabled most of my startup programs, everything but some audio drivers and the Task Scheduler Congif Tool.

Another thing that I've noticed is that the problem only occurs when the computer has been shut down for more than ~30mins. If I were to shut it down right now, wait a minute, and re-boot, it would do so correctly. Not sure if this provides any sort of clue.
