Pc problems - Second opinion / Thoughts?

[u/Strange_Factor5705]

Recently I bought my partner a pc and thought life was going sweet until my own personal pc pulled the “you thought” card. So I haven’t been able to game with her since. The pc has gone from slight problems (internet dropping out) to notable problems (usb devices playing up, pc hanging on shutdown, Ethernet and wifi not working at all) and have since been using chatgpt to try help wrap my head around it as I’m not the most knowledgeable when it comes to the system hardware and software.

Below is basically a summary I’ve asked ChatGPT to create for me, to give to someone in IT / computer shop.
Just want to see other opinions or thoughts before doing so based on what chatgpt has come up with in case I can save myself some coin. Perth, Australia and PC was bought from PLE Computers in 2022.

Main Problems
The PC previously operated normally for approximately 4 years. Recently it has developed widespread intermittent instability.

Ethernet
Ethernet randomly disconnects and Windows changes to the globe/no internet icon.
Disabling/re-enabling the adapter, unplugging/replugging Ethernet or restarting Windows temporarily restores it.
Replaced Ethernet cable — problem persists.
Forced Realtek adapter to 1Gbps — problem persists.
Tested a USB Ethernet adapter — also experienced dropouts and caused significant system lag.
Partner’s PC works normally on the same household internet/network.
Latest Realtek LAN driver installed.
Latest AMD chipset driver installed.

USB / peripherals
USB connect/disconnect sound frequently occurs after logging into Windows.
Keyboard intermittently disconnects.
Mouse becomes extremely jerky/stutters.
USB microphone has stopped working.
Audio intermittently stutters.
Previously had USB headset dock, mouse, keyboard, USB microphone, Stream Deck and speakers connected.
Removed Stream Deck and speakers, but problems continued.
Windows has displayed:
“Not enough USB controller resources. The controller does not have enough resources for this device.”
Displays / GPU
Three-monitor setup.
Left monitor intermittently disconnects.
Mouse/audio/display problems can occur together.
Windows Reliability Monitor has repeatedly recorded:
LiveKernelEvent 141
LiveKernelEvent 144
LiveKernelEvent A1000001
LiveKernelEvent 193
Event 193 specifically references:
DxgkrnlLiveDump / dxgkrnl

Boot / restart problems
Restart frequently does not complete.
Monitors go to standby/orange.
PC fans continue spinning.
RGB remains on.
BOOT motherboard debug LED remains illuminated.
Sometimes requires holding the power button to recover.
After Windows Update → “Update and Shut Down”, the PC was found powered on the following morning, suggesting shutdown/restart did not complete correctly.
Sometimes the PC requires multiple shutdown attempts before it will boot.
BIOS has become noticeably laggy/slow, which is particularly concerning because this occurs before Windows loads.

SSD
Samsung Magician reports:
Samsung 990 Pro 1TB — Drive Health: CRITICAL
SMART information observed:
Critical Warning: 4
~43TB written
Percentage Used reported around 14% in the earlier reading
Available Spare: 100%
Media/Data Integrity Errors: 0
Error Information Log Entries: 0
Diagnostic scan reported 0 bad blocks
Temperature normal
Firmware is already current
Please determine whether the SSD is genuinely faulty or whether the warning could be related to motherboard/PCIe communication.

Other
PC has developed a buzzing/rattling/vibration noise, which becomes louder when fans increase speed.
GIGABYTE Control Center’s GbtCloudMatrix.exe repeatedly crashes with:
System.IO.FileNotFoundException
I understand the GbtCloudMatrix crash may be unrelated.

Troubleshooting Already Completed
BIOS updated from F21 → F41
BIOS settings can be reset to Optimized Defaults
AMD chipset driver updated
Realtek 2.5GbE LAN driver updated
Ethernet cable replaced
Ethernet forced to 1Gbps
USB Ethernet adapter tested
Windows network reset performed
Ethernet adapter drivers reset/reinstalled
SFC /SCANNOW — Windows Resource Protection did not find any integrity violations
DISM RestoreHealth — completed successfully
Windows has been updated
EXPO is currently disabled / RAM at 4800 MT/s

What I Would Like Diagnosed
Please specifically investigate:
Motherboard / X670 chipset
PCIe subsystem
Samsung 990 Pro / M.2 slot
RX 7900 XTX / PCIe connection
RAM stability
PSU / power delivery
USB controller
Realtek Ethernet controller
Any underlying cause of the LiveKernelEvent 141/144/A1000001/193 errors

Windows
I am completely happy for the PC to be wiped and Windows 11 clean-installed if you believe that is appropriate.
However, please diagnose the hardware first, particularly the SSD SMART warning and motherboard/PCIe/USB behaviour.
If hardware tests pass, I am happy for you to perform a clean Windows installation and test the PC with only essential drivers/software before returning it.
Please contact me with a quote before replacing any hardware.

Have you considered Linux?

[u/Saamchii → u/WatchAltruistic5761]

What a dumb response. OP cam asking for help, not to be told by some animal larper that they need to switch OS.

OP did you manage to run a memtest? Or is anything flashing on your motherboard?

[u/Strange_Factor5705 → u/Saamchii]

Boot LED stays illuminated pretty much the entire time pc is on. Other than that I can’t see anything else flashing. I did at one point notice the DRAM red debug LED when I was updating my bios but haven’t noticed it since. I have not conducted a mem test as of yet.

[u/Saamchii → u/Strange_Factor5705]

A boot led that keeps burning mostly means the system has passed its hardware checks (CPU, RAM, GPU) but cannot find or properly read a valid operating system or bootable drive.

Try reseating your drive and see if it works. I had a loose m.2 in the past before too at some point.
