Failed to boot

I have a slight doubt, look at your motherboard
at the location of the cooling system, below, it can be seen on the image of the motherboard
there is a chip i think

out, a similar model, and of the ones I watched, it is just mentioned embedded video

 Kazon-UF motherboard specifications.

 HP Pavilion 24-x001ni All-in-One 

Integrated graphics

• Integrated Intel HD Graphics

look at the difference, no chip
but see the list, I could not compare everything

if that's it, I'm afraid he'll have to replace the motherboard *
Indeed for the SSD m2 it was obvious!

Hi,

There is a graphics chip on the motherboard somewhere. Can't say if the chip is integrated, soldered, or socketed.

Not going to debate this further since the hardware problem is undefined.

One can start troubleshooting other components by removing one component at a time such as replacing the external power supply, disconnecting the HDD, then the M.2 SSD, then the RAM to check for a POST error code. Now replace the RAM, then replace the CPU. Well, now you are down to the motherboard or the graphics .
