Flickering issue on Acer Aspire A715-72G

Will be as short as I can:
Briefly, I get this flickering on my screen (attached below). Tried manufacturer's drivers, performed a clean installation, etc. Nothing has helped. It feels like a piece of my screen rapidly goes down and then up very fast (on the picture the windows icon slides down rapidly and then ascends again). Also, the flickering disappears when I use 100% brightness. And would like to notice that sometimes I can use it for hours and there's no flickering on any brightness. But then it appears again. Feels like something happens when it wakes up after sleep mode or idk.. Maybe I go wrong at this point. Also plugged in another monitor via HDMI. No issue on it. Always everything works properly. So, please, help me. I can't even restore a clean manufacturer's setup of my laptop, 'cause everything has been removed during a clean installation of Windows and I didn't save the initial image on my USB.

Please don't post multiple threads and PMs on the same issue. It only tends to unnecessarily confuse, delay and create repeat responses. If you have a backup of the original factory-installed HDD setup, then use it to return the system to a factory fresh state. If you don't have it then contact an ACER regional service center directly to see if a USB factory recovery pendrive is available. The BIOS version you claimed was factory installed was 1.26, NOT 1.28 as suggested in your PM. Jack E/NJ
