ASUS ROG STRIX G531GT-BQ024T Display blinks for a second

[PhoenIX09]

I have a ASUS ROG STRIX G531GT-BQ024T
8 GB RAM 1TB HDD/256 SSD
Although being an SSD it's boot timing is too slow it takes around 40 seconds to load.
Also whenever you boot your system either way when it's plugged in or on batttery the screen blinks for 1 second for that second the screen goes black and after a second it's normal I've updated the drivers and no this isn't a driver issue
Also this happens not only when booting but also when even when u plug in and unplug the charger as in its changing the mode pls help if anyone can I just bought it yesterday 😭
Also plz any suggestions of how to reduce my boot timing and at boot the ram usage is 4 gb😑

Hello PhoenIX09,
Well... as you even know it is switching modes, then it's normal.
The refresh rate is changing, like when plug in it's 120Hz and then when unplug is 60Hz.
And the blinking 1 time is also normal, happens on other model as well.
Thank you.
