Hp Pavilion 15-E freezing

[Retrocomputer]

Hi!
I have a strange issue with an HP Pavilion. I got it with no hard drive, it has no problens running BIOS, it reads everything attached to it properly (Hard drive, RAM...), but when I try installing Windows it freezes up completely. If I try booting in UEFI mode, it freezes almost instantly, it shows the HP logo and the circling balls underneath freeze after not ever a complete circle. If I boot in legacy mode, it works for a minute, it loads the installation process, then it freezes at random, maybe while selecting the OS version, or while selecting the hard drive to use.
The only thing to do is hard restarting it.
The mobo is a DA0R76MB6D0.
I've already tried detaching everything (wifi card, HDD, ODD) and swapping out the ram. The USB key is working great on other PCs.

Where can the problem lay?

Thank you so much.

Flash bios and see for any changes back up old Dump

I will have to remove the BIOS chip from the mobo for sure... Was thinking about that, I even tried flashing a new version as per HP instructions but to no avail, the PC doesn't even recognize the BIOS file. I'll have to source a known good dump though. Do you think that the BIN file from the HP site is enough?

Thank you.

Unlikely it's the BIOS, but worth a try. Could be a failing FCH.

I encountered similar problems and were due (display, keyboard, video chipset).

I agree with piernov. Seems like failing FCH. Amd' chipset are known to fail on this mb.
