FX553VE-DM318T(FX553v) not POSTING

Does it have to be exact same bios chip?
i have mx25c6473f from a desktop motherboard.
Both are 64 mb.🤷♂️

This will be my segue into owning a hot air rework station.

Opening the BIOS in UEFITool - Descriptor region says this:
Flash chips in VSCC table:

C22017 (Macronix MX25L64)
EF4017 (Winbond W25Q64)
EF6017 (Winbond W25Q64)
C84017 (GigaDevice GD25x64)
20BA17 (Micron N25Q064)

Either one is compatible, if the other chip you have is actually MX25L6473F it looks like it's compatible, according to the datasheet for that chip the device ID is C2 20 17, which is in that list

Replaced my bios ic sucessfully.
from w25Q64 to 25L64.

My system still freezes when i press esc key to interrupt boot sequence. (To get into bios)

i.e. gets stuck at asus splash screen.

If i try get into bios using advanced startup options.
My pc still freezes but on a blank black display after asus splash screen.

I came across this https://www.youtube.com/watch?v=P0YzSWBm-TQ
but since i only have one display, i donot know how this applies.

Sometimes(after i have not used my pc for some time) my pc will have issues with posting.
I have noticed that my cpu and my chipset will get hot.
So i wait for them to cool off and then try starting again, it works.

When my pc starts and run smoothly this heating is absent.

I think i have figured it out.
its my ssd.
If i remove my ssd, my bios boots up fine.

But my ssd is new.
Orion o700, 1 tb

How to verify if my ssd is faulty, or port or a compatibility issue?

Only way to test if SSD is faulty, is to test it on another PC if it causes the same issue
As PCIe Gen 4 SSD should be backwards compatible with PCIe Gen 3 host, like your laptop, it will be limited to Gen 3 speeds (max 3200MB/s) so there's no point spending more on a Gen 4 SSD, unless you plan to reuse it later on a newer PC
Amazon reviews from the link you posted say that it runs hot, assuming it draws more power than a Gen 3 SSD

I'm assuming the BIOS detects properly the SATA HDD, and you can access its contents from a live USB

Measure resistance across B5301, it should be 0 ohm, it connects 3.3V to the M.2 connector, your board either has that part installed, or it has a solder blob across JP5101
If B5301 is faulty, you can close JP5101 with a solder blob
If instead of B5301 you have a solder blob at JP5101, ignore what i said

I have used my ssd to read and write, and also checked for bad sectors on the same laptop, from booting to windows. All test passed.

I suspect my motherboard can only support 128 gb ssd, because the only place i have issue is bios.

And my bios/motherboard cannot handle such high capacity causing issues.

today i will def. check my laptop, after work though.
see ya!

May be an unsolved BIOS bug then, if you have another M.2 NVMe SSD you can try, preferably an older one PCIe Gen 3
If you can boot to Windows normally, but not enter BIOS setup with the current SSD, but removing it allows the system to boot, i don't know what could cause this behavior as i saw posts from people who claimed to upgrade with NVMe drives without issues here:
https://www.myfixguide.com/asus-rog-...grade-options/

Also if you can source an M.2 SATA SSD you can try that one too,
