Windows 10: Hard Reboots no BSOD in low-load situations for new PC - changed most HW already

Dear all,


I've built my own PC, being an IT guy and doing this for more than 30 years. Now I'm having a nasty issue where I'm struggling to resolve it.


My components all new:

Be Quiet Straight Power 11 550W

MSI B550-A PRO

AMD Ryzen 3700X

be quiet! Shadow Rock TF 2

HyperX Fury 2x8GB DDR4-2400 listed as compatible by MSI for the B550 board

ASUS GeForce ROG STRIX RTX 2060S 8G EVO GAMING

WD Blue 3D NAND 1TB SATA 2.5"

Windows 10 20H2


Problem:

I built the PC at the beginning of December 2020. Since the start I'm having reboot issues. The PC usually reboots every 10-60 minutes. It is a hard reboot without a BSOD. There is no minidump or memory.dmp file. The System Log shows a Critical Error Kernel-Power ID 41 each time after the reboot.

The interesting part: It only happens in low load situations, nearly exclusively when surfing the internet e.g. reading news pages, or when installing software. During those past 2.5 months, it never ever happened in a high load situation, i.e. when gaming and I gamed many hours. It also didn't reboot when I e.g. ran Cinebench R20 for 15-20 mins. Temperatures for CPU, System, etc. are all in the very green range, no issues here.


What did I do so far:

• Completely re-installed Windows 10 twice after initial installation
• All mainboard drivers, plus mainboard firmware on latest release
• Was running Memtest64 and the Windows Memory Test -> all fine
• Exchanged both RAM sticks with brand new ones same type
• Exchanged Power Supply with another proven-to-work BeQuiet 550W
• Exchanged SSD
• Exchanged GPU
• Added USV with Power Surge protection although power is absolutely stable where I live

The only components I have not exchanged so far is the CPU and mainboard. Before I do this, I wanted to ask for any advice. Could this be software related or is it a known issue with my hardware combination? What is the most likely root cause, given all actions I already took?


FYI, I only had a BSOD once. The minidump file pointed to ntoskrnl.exe which I guess is neither a big surprise nor does it really help, I think.

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?

 

Windows running slowly in specific situations

Over the last few days (since maybe Thursday but definitely Friday) my Win10 machine has been running slowly in certain situations. The programs iTunes, GSAK, and Unreal Tournament 2004 run slowly in general, much slower than my new hardware has been able to output since I bought it less than two months ago. Other programs are substantially slower than normal to load, but act quite fine once they've been loaded (Sid Meier's Civilization V and Overwatch are two notable exmaples - they take up to six times longer to load than they did this time last week). The change was sudden but not noticeable straightaway.

One further change I've noticed is that whenever I go to shut down or reboot the computer, it tells me it's "Getting Windows ready" despite there being no updates to my knowledge. It tends to hang on that screen for some time before it actually shuts down or reboots - I'm not sure how long it takes as I often lose patience and go and do something else, but it's more than expected.

Steps I've already tried:

• rebooting
• antivirus scan
• uninstalling programs I've installed within the last week
• rolling back Windows updates (which I've found to be basically impossible)
• cleaning up the fullest hard drive (I've more than doubled the free space on it)
• updating my video card drivers
• defragging all three hard drives

Any ideas?
