Boots to BIOS but restarts when trying to boot any drive

[Katze]

I have a B365M Pro-VDH with an i5 9500.

 

It posts and can access the BIOS just fine, and it can sit there as long as it wants, but as soon as I try to boot from a drive with windows, or a USB with a windows installation, it will restart at some point.

Some times it will last 10 minutes, others 5 seconds.

I noticed when it restarts, the CPU Debug LED lights up for a sec just before it loses power and restarts a second later.

 

I have tried moving around RAM, swapped drives, reseating the CPU etc.

 

Any ideas?
bad PSU? CPU? MOBO?

Have you tried resetting the cmos?

Resetting no, but when I was swaping the RAM around, it was loading defaults anyway.

This is a new build and not an existing working system that stopped working?

 

I would suggest stripping the system down to the bare minimum to run (Single ram stick, use the integrated graphics only, no internal drives) and see if the Windows installer will boot and hold off USB.

Yes new build.

 

I have stripped it down and used the box as a makeshift test bench, I have not however tried to see if it will hold on the USB without a drive connected.
I'll try that, thanks.

These are my current thoughts of possible problems with what is known.

1. The bios is too young, and not playing nice.
2. The chipset is shot (Because the chipset normally deals with USB and drives).
3. An item connected to the chipset is faulty or not playing nice (Onboard Lan, Onboard audio, ext...).
4. The windows install is too old to recognize or work with the current hardware (Rare problem with modern Windows).
5. Some overclock we don't know about is making the entire system unstable. (Could be heat related).
6. The system is resetting from overheating.

Spitballing at this point...

Memory issues.  Is your RAM on the QVL?

Looks good. Only one BIOS version so you should be good.

Haven't had time to work on it today, but will be giving it another tomorrow.

Just tried to boot it to a USB with no drives connected, same issue.

I tried another USB with windows on it, same issue.

Is anything in the system overclocked?  Things like XMP count.

[Katze]

Its all stock, nothing has ben changed and I have reset the bios multiple times.

I bought a new motherboard and the CPU and PSU work fine in it, no random restarts.

 

It seems the board was faulty, being sent back.
