So I have the all-in-one A5600U-UB25 because my grandmother did something to it where it won't go past the black screen with the green acer logo on it. I don't ever see anything else. When I power it on, it loads that screen with a beep, the numlock light on the keyboard comes on for about 2 seconds, then the keyboard light goes out and it stays on the acer screen for about 5 seconds, then boots up again with a beep. And that's all I can get it to do. I've tried tapping both F8 and F12, I've tried holding down Alt then tapping F8, and I've tried tapping the spacebar, all to no avail. I am willing to buy a new Windows 10 key and OS, but I don't want to spend the money on it yet unless I know I'll be able to get it to the Boot Menu to be able to load it from USB since there's no CD drive that I could find on the pc itself. Is there anyone who can help me out with this? I don't mind being told that I'm doing everything wrong, I just wanna figure out what's right and what will work.
Thanks so much in advance for anyone and everyone's help!
