Hi guys I have a pretty serious PC problem so I hope some of you can help me. A few days ago during a shutdown Windows hangs on shutdown by switching to a black screen that leads the PC to a loop of blank reboots terminated by a direct shutdown of the PC using the power button. Subsequently, the PC was no longer able to boot, not even reaching the BIOS, the boot phase stopped with the motherboard with q-code 94 corresponding to the "PCI Bus enumeration" phase and the VGA led lit and then the boot retries automatically without ever reaching the BIOS and showing no video signal at all. Last night, two days passed (after trying various cmos, reboots and removal of power to discharge the capacitors) the PC randomly boots and resets a Windows error. Everything works perfectly (tested with cinebench r23, Crystal diskmark and some games) and even turning off and on again no problem of fate. After hours of use, convinced that everything had been resolved, I turn off the PC again and Windows freezes in the same way, bringing the PC back to its previous state. Today I tried for 6-7 hours to overcome this continous boot loop with constant code 94 and no video signal on the screen, but i wasn't able ti solve it and I have no idea how yesterday the PC managed to post. I suspect or a software problem of corruption of the BIOS due in some way to Windows or some hardware problem of the motherboard maybe, even if in my opinion the problem is really illogical and difficult to understand and appeared suddenly. Right now I have tried to remove the battery of the mobo, tried a boot without the main nvme which contains windows, tried to update the bios using the flashback usb port, but I have not tried yet to move the video card to other slots or such solutions as the system is cooled by a fairly complex double custom loop which takes time to take apart.
If anyone is able to help me I would be really grateful.
PS: we are talking about a really high-end rig (5950x, Asus dark Hero, 3090, ax1600i) each component cooled with custom loop
