Just an FYI for y'all.

I've been fighting BSOD, and a constantly-returning Q-code 94 (PCI bus enumeration) on my new build, for 3 days.

Crosshair VIII Hero, AMD 3400G cpu, AMD RX 5500 XT GPU, 2 x G.SKILL Ripjaws V Series 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 4000, and two Sabrent Rocket PCIe M.2 sticks.

I tried 3 different video cards, three different monitors, BIOS from 1302 to 2404, swapping DRAM, and GPU in 2 of 3 slots.

It turns out that one of the Sabrent Rockets was flaky.

Hope this helps someone!

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 nvme with the os, 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

Whenever I first start my PC, it gets stuck at code 94 and the monitor stays blank. The only way I can solve this, is by restarting my PC after having waited for a while. I searched my trough my PC for damaged files, but couldn't find any. This is annoying since it also happens when I restart my PC for downloading games or softwares.

Hello So I am having a pretty hard time with my new setup. I have been using a low end pc for the past year now and I am tired of the low FPS
(I7-3820k,

Asus p9x79 deluxe motherboard,

Corsair vengeance Blue 16 gb ddr3 ram 4 sticks 4-4gb, Corsair h100 92 cfm liquid cpu cooler,

Nvidia nfs 310 graphics card,

Kingston a400 480 gb ssd

WD Blue 500gb ssd

thermal take tr2 600w psu,

and the NZXT phantom 410 for my case)
I Finally got all the parts to upgrade after saving up for a while

(I7-5820k, Asus X99 deluxe motherboard,

Corsair Vengeance RGB Pro 32 gb ddr4 4 sticks 4-8gb,

Corsair h100 92 cfm liquid cpu cooler (same one),

MSI Ventus GP OC Geforce RTX 2060 SUPER 8 gb,

Kingston a400 480 gb ssd

WD blue 500 gb ssd

thermal take tr2 600w psu (same psu),

and the NZXT Phantom 410 (same case) )

I started and completed the build and while testing before putting it in the case I got error code 94, And on top of this I got no display on my screen. I thought at first it was my Graphics card, so I started to swap it around in the PCI ports and none of them worked. So I used my old card and it did the same thing, No display, even after swapping that one around too.

Then I thought it was my cpu so I took it out and checked the pins on the motherboard and I think 2 of them were slightly bent so I fixed them. I reseated the CPU and re-applied thermal paste, and nothing. The same code and no display.

So then I thought it might be my motherboard, so I swapped it out for a spare one I have (Asus rampage V extreme) and I got the same code and no display.

Then I just tried other things, Swapping my gpu around the PCI slots multiple times, Booting it with my OS ssd only, Trying only each individual ram card at a time, and still nothing.

I need help please, Any ideas on what to do?
