Dear all

This is my first desktop PC that I set up on my own.

System:
MSI MAG B650 Tomahawk WiFi (MS-7D75)
Ryzen 7 9800X3D
TR Peerless Assassin 120 SE
Viper Venom 2x16 GB DDR5 6000
NVIDIA GeForce RTX 5070 Ti
Samsung 990 Pro 2 TB
be quiet! Pure Power 13 M 750W
Windows 11 Home 24H2 (build 26200)

Issue:
My PC is fully stable during normal Windows use and AAA gaming, but it consistently has problems only during startup/shutdown/restart transitions:
  • Cold boot: the first boot always freezes on the MSI motherboard logo / spinning loading animation
  • Windows restart/shutdown: Windows closes apps, reaches the very late stage of restart/shutdown, then freezes hard with the hardware still powered on
  • Pressing the Reset button makes the next boot succeed
  • I have also had USB-related oddities, including:
    • wireless mouse lag
    • freezes when trying to change USB power settings
    • freezes in the same style when interacting with a USB device in Device Manager
So the system is stable under load, but unstable during boot / restart / shutdown / device-power transitions.

What has already been tested:
  • Windows Memory Diagnostic: no errors
  • EXPO: disabled
  • Fast Startup: disabled
  • Hibernation: disabled
  • SFC /scannow: clean
  • DISM /RestoreHealth: clean
  • Pagefile: enabled, system managed
  • No BSOD, BugcheckCode = 0
  • Kernel-Power 41 appears, but only as a consequence of forced reset
  • WHEA-Logger gave no useful clue
  • DCOM 10010 traced to Microsoft.WidgetsPlatformRuntime, likely unrelated
  • Safe Mode: boot/restart works normally
  • Clean boot: did not help
  • Moved keyboard/mouse from USB receiver to Bluetooth: no change
  • Disabled Memory Integrity / Core Isolation for testing: no change
  • Updated to the latest stable MSI BIOS (March 2026): no change
  • Disconnected front USB-C and front USB 3.x headers from the motherboard: no change
  • Tested with one RAM stick only in the correct slot: no change

At this point I suspect something around: USB/Device Manager motherboard power management issues, motherboard / chipset / USB controller / ACPI-power path
  • or less likely, some physical build/mounting issue as this was my first - I also had issues installing CPU fan screwing the bolts causing it to move above the CPU marked with thermal paste a lot, but again - I believe this would have popped up during intensive AAA gaming - and it had not - games are smooth as hell
Has anyone seen this behavior specifically on B650 Tomahawk + Ryzen 9000 / 9800X3D, where first cold boot freezes but reset makes the next boot work, and Windows restart/shutdown freezes at the very end?

that's a cool build you've got there. hope you are able to sort the issue(s) out soon.
what is the exact part number of the memory you have?
you're using the (assuming you live in the USA) 20-March-2026 BIOS (7D75v1P8) ?

Thanks, quite a disappointment to be having this issue, assuming this is my first desktop as an adult (36, yo) (was using a gaming desktop before).
Part number - can you please amplify which one I should check please.
Living in EU, using this one, yes

Here is an example memory part number: KF564C32BBEK2-64
Kingston FURY Beast 64GB (2x32GB) 6400MT/s DDR5 CL32 Desktop Memory | AMD EXPO | Kit of 2 | KF564C32BBEK2-64
I doubt memory is the issue, but I guess we have to see it on the MSI Memory compatibility list.
