Question Hardware incompatibility on new build ?

[Moriz31]

Good morning everyone!

I recently assembled a new PC and installed Windows 11 on it, and I’m experiencing some boot issues:
Every time I start the PC, about 20-30 seconds after turning it on, the system starts to slow down. The window animations (when I move them) stutter, it takes extra seconds to open applications, and strangely, if I try to play a video on YouTube, it plays in slow motion with the audio stuttering. These problems occur almost every time I boot up and can last anywhere from 1-2 minutes to 10 seconds without any apparent reason.

I’ve disabled almost all the startup apps, keeping only the Realtek audio driver and Windows anti-malware.
I also tried starting the PC without opening programs in the first few minutes, but it still starts to slow down at some point. When checking the task manager, I don’t see any abnormal resource usage, and there’s nothing particular in the event viewer. I checked the temperatures, and I don’t see any abnormal spikes during boot.
I’ve also tried reinstalling the drivers and updating the BIOS.

Can anyone help me? I don’t know where to turn next.

• Mobo: Asrock X870 Pro RS
• NVMe SSD: WD_BLACK SN850X 2TB
• Windows 11 Pro 24H2
• PSU: Sharkoon silentstorm coolzero 850w

RAM: 2 Corsair Vengeance 32GB 6000MHz DDR5 sticks
Got a link to the ram kit you're working with?

Mobo: Asrock X870 Pro RS
BIOS version for your motherboard?

Disable iGPU in BIOS, then use DDU to remove all GPU drivers(Intel, AMD and Nvidia) in Safe Mode, then manually install driver version 566.36 in an elevated command, i.e, Right click installer>Run as Administrator.

Is the memory installed in slots 2 &4 away from the processor?

Yes, the RAM sticks are in the correct slots. (I use the EXPO profile from bios)
Yesterday I reformatted the PC, installed all the drivers, and updated the BIOS, but the problem reappeared. (BIOS version 3.20)

Have you tried booting with the iGPU and with the 3080 uninstalled?

As soon as I noticed the issue, I tried disconnecting both monitors one at a time, and I also tried connecting one to the motherboard, but the slowdown didn’t stop.

Did you even uninstall the graphics card while testing the iGPU? Does the PC operate as expected after the initial weirdness? What is all of the hardware, including USB devices, that are plugged in to the PC?

Yes, exactly, after those 2–3 minutes of slowdown, the PC works perfectly (no abnormal temperatures, crashes, or similar issues) until the next boot.
I've noticed that when I restart the PC several times in a row (for example, when installing drivers or making changes in the BIOS), the issue doesn’t always occur. However, if I start it from a powered-off state, it happens 99% of the time.
Currently, I have connected via USB: a microphone, keyboard, mouse, a dongle for wireless headphones, and a USB extension cable.

I installed the drivers following your instructions, but the problem persists.

I have some errors and some warnings in event viewer but idk if it is correlated

errors:
- TPM-WMI 1796: Secure Boot update failed to update a Secure Boot variable. Error: Secure Boot is not enabled on the computer. For more information, see https://go.microsoft.com/fwlink/?linkid=2169931

Try booting with no peripherals connected except the mouse, keyboard, and the monitor attached. Unplug everything else.

I tried it but the problem still exist:

I tried some tests on the hardware:

-Replaced the SSD with an old one I had
-Since I don't have any other DDR5 RAM sticks, I tried using just one at a time
-Disconnected one of the monitors (I have two), alternating between them
-Used the video output from the motherboard
-Changed the RAM profile (from EXPO to XMP)

If I had to speculate, I would say there is something funky going on with either the CPU or the Motherboard. Are all of the pins in the motherboard socket good? Any bent or missing? One thing you could try to do is install LatencyMon and have it running while the slowdown is occuring. This may give us a clue as to what is going on.
