Hy guys i have this Acer Laptop A315-21-29NS with motherboard model DA0ZASMB8D0 REV D that's restarting when trying too boot in legacy or uefi i have tryed different bootable flash drives in all the ports, tested the onboard memory (all good), tryed to boot from a ssd with windows already preinstalled , it crashes, i have programed another clean bios, same thing , sometimes i get white noise image, most of the time it restarts after reading the bootable usb flashdrive. What should i try next?

It seems that your model does not have a dedicated graphics card, everything points to a problem with the graphics card integrated into the processor or a problem of lack of contact of some balls under the processor. Without tests it is not easy to make an accurate diagnosis. I don't think it's a BIOS problem

What should i measure on the board or test to be sure its the cpu, and then i can try a reflow.

To me,it seems like onbaord memory module fault. Does it have a ram slot?

It has a ram slot available, like i mentioned i have tested the onboard memory and it has no errors, last thing that i could try without intervention on the board would be a bios with the onboard ram disabled if i could get one.
