Help ! ASUS K53SD ASUS REV.5

[CICCIVALENTI]

my friend is seems like a pch or gpu proplem
on the other side of the motherboard (bottom) there are the cpu,pch and gpu chips
the nvidia card is not integrated card
if you have some expirance i sugest to isolate the nvidia gpu first or what it called (dis to uma)
search it on the internet and see the result

I think we are getting closer to the solution.
I think I understand, the procedure you suggest would be this one from this guy on YouTube? https://youtu.be/KuUxktKC8_Q?feature=shared

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

OK you need to check what is the combonent that gettig hot is it the gpu chip with (nvidia) word on it
or the pch that has big letter ( i ) on it
i still sugest to try boot the lap top without hard drive because some times it is just slow hard drive that slow down the
boot up
