so is one of the gpu becoming too hot? laptop normally would shut off..if not keep problem search , you can look find if shorted around the bios chip and gpu etcetera, also can use a donor gpu to test if you can lean one or u can get an usb laptop tester for it ..just to add some ideas

okay i see, but i persist trying the basics for all possible missteps i assume you put back old hdd (if still working) to check but yet and again u need let dryout laptop for any power left (cmos reset and let it disconnect for a while) and check battery connected as well disconnected and connect again only on wall source , and some ssd can totally go dead with a powershoratge or a heavy shake(like i had once with an ssd form ebay) and also an other time it was a dead ram/ramslot preventing device from accesing any Os...

hi like Lisa Su suggested trying F1, theremore and first of all you have to check all Bios simple settings ! i have had few asus laptops having hanging on logo because of missing setup simple steps as to start with : do you have any os like windows or any other already installed if yes the next question is : did you play with the bios settings by any coincidence? or otherwise a bios for this asus you can find on the net (not as impossible as it looks) and you try with ch341 againfirst read if can and backup before any flashing. hope this helps a bit
