Hey Stefan,

A couple questions to kick off the troubleshooting process!
Are you overclocked or undercooked at all?
Are BIOS and drivers up-to-date?
How are your temps generally?

No it isn't overclocked. I use the fan key to switch between silent / performance and turbo. I have tried all modes. Even the windows mode.

Bios and drivers should be up to date. I checked them recently but I can check again if you want. I got the available drivers from the asus website. Date 12/Mai/2022

Temperature? It is fairly high. It can be close to 90 degrees or even higher as far as I remember. It's 86 max when I set it to turbo right now doing not much for applications.

I actually opened the laptop and cleaned the fans as good as it goes. I haven't tested it afterwards. They were dusty. There is also a bit of surface rust on the USB ports

Thanks

Cleaning the fans did reduce the temperature. However the freeze still happened again. Yesterday was ok all day. I did run a complete check in the MyAsus windows app. It didn't show any errors.

Install LatencyMon and check with it.

What am I looking for? - I reinstalled all drivers from the ASUS website because the main comment got red in the LatencyMon window. After that it stayed black but lots of errors. I post the conclusion here first:

CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs,
clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system
appear to be executing for too long. At least one detected problem appears to be network related. In case you are
using a WLAN adapter, try disabling it to get better results. One problem may be related to power management,
disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:16:58 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a
hardware request from the moment the interrupt service routine started execution. This includes the scheduling and
execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait
state in response to that event.

Highest measured interrupt to process latency (µs): 1303.50
Average measured interrupt to process latency (µs): 6.501145

Highest measured interrupt to DPC latency (µs): 1293.80
Average measured interrupt to DPC latency (µs): 2.022393

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but
backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory
from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to
interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs
were hit.

Process with highest pagefault count: chrome.exe

Total number of hard pagefaults 6761
Hard pagefault count of hardest hit process: 1872
Number of processes hit: 66

Looks like all the problems are caused by Microsoft drivers or processes. Should I go back to windows 10? Is the Laptop not really well suited for windows 11?

I would go back to Windows 10 until the big update on Windows 11

A few more thoughts:

I have the laptop in the car most of the time so it gets a lot of vibrations. It might be something loose inside. I can't see anything though. Sometimes I work for a couple of hours and then I move the laptop and it freezes the moment I move it. But then other times I can shake it and nothing happens.

The whole latency thing might not be great but it might also be not the reason for the problem. I have worked with the laptop under windows 11 for months without the slightest problem. Until I installed an updated version of Unreal 5. This might be a coincidence. Because first it only crashed while using Unreal 5 but now I have it crashing/freezing sometimes if it only runs hardware monitor and latency monitor.

So maybe its even a combination of things. Loose hardware or defective hardware that only causes occasionally problems. Returning to factory state would be something of a last option. But I get the feeling it will happen even then. Anyway - I'll have to reset it eventually I guess just to make sure where the problem is.

Anyone knows if a repair would be possible? It's a $ 3000 laptop so it should be able to get repaired, or?
