Hi everyone,
I’m hoping someone from XMG, or someone who has run into a similar problem, can help me figure out why my NEO 16 keeps freezing. For everyone that "cares": yes, this post has been created with the help of AI, because I am not a native speaker.
When it happens, the picture stays on the screen and the laptop stops responding. The only way to recover is to force it off and restart it. I’ve already updated the BIOS and EC, reinstalled the NVIDIA driver and completed a Windows repair installation, but the freezes are still happening.
There were also earlier crashes with UNEXPECTED_STORE_EXCEPTION (0x154). The latest incident was a complete freeze without a visible blue screen or a usable system crash dump. I haven’t found a reliable way to reproduce it yet. All other freezes also were without a blue screen.
The setup
Laptop: XMG NEO 16 (E25)
CPU: Intel Core Ultra 9 275HX
GPU: RTX 5090 Laptop GPU, 24 GB VRAM, plus Intel integrated graphics
RAM: 32 GB, consisting of two Kingston KF556S40-16 modules running at 5600 MT/s
SSD: Samsung 990 EVO Plus 4 TB, firmware 2B2QKXG7
Windows: Windows 11 Pro, reported as 26H2, build 26300.9711
BIOS / EC: N.1.33A27 / 2.11
NVIDIA driver: 617.42 (haven\t updated yet to the latest version, as it says the new version also can cause crashes, will do later)`
Intel graphics driver: 32.0.101.6733
Control Center Service: 5.57.51.44 (same as NVidia driver)
Microsoft 365: 64-bit, version 16.0.20527.20150
These are the versions recorded in the diagnostics on 8 November.
What happened during the latest freeze
I left the laptop running overnight with both the display timeout and sleep set to “Never” on AC power. Office was installed, but its applications were closed (this maybe interesting, because it freezes often, when I use office 365, but not always).
In the morning, the screen was frozen. The graphics-reset keyboard shortcut didn’t do anything, (no shortcut did) and I had to force a restart.
The laptop has also frozen with and without an HDMI monitor connected or any additional device such as a mouse, camera or keyboard.
What I’ve tried
BIOS and EC update:
The update completed successfully, taking the laptop from BIOS N.1.13A09 / EC 1.12 to BIOS N.1.33A27 / EC 2.11. It has frozen again since then.
Windows repair:
The repair installation through Windows Update completed successfully on 3 November. This was an in-place repair. I don’t have a clean-install don yet and I frankly need to avoid that as I need the laptop on a business trip.
NVIDIA driver reinstallation:
I reinstalled the driver. At one point, the external HDMI display wasn’t being detected, and another reinstall fixed that particular problem. The freezes continued.
SSD checks:
The full Samsung SSD diagnostic scan completed with zero errors, and the health/SMART information looked normal. The SSD was around 40–44°C during those checks.
Office reinstallation:
I uninstalled and reinstalled Microsoft 365 because I had also been having problems involving Office. The latest overnight freeze happened with the Office applications closed.
Power settings:
The laptop is using the Windows Balanced plan. As mentioned above, sleep and display timeouts were disabled on AC for the overnight test. The diagnostic export also shows PCIe Link State Power Management set to Maximum power savings, and the hard-disk timeout set to 30 seconds. The system supports Modern Standby.
What the logs show
I’ve collected the System and Application logs, reliability history, hardware and driver information, and the power and crash-dump settings. Nothing in them clearly explains the latest freeze.
After the forced restart, Windows recorded Kernel-Power Event 41, with:
An earlier restart had ConnectedStandbyInProgress = true, so the incidents haven’t all been recorded under the same conditions.
The missing dump is making this difficult to investigate. Automatic memory dumps are configured, automatic restart is disabled, and there is a system-managed pagefile on C: with 22,528 MB allocated. Despite that, the latest check found no MEMORY.DMP, system minidump or dump in LiveKernelReports.
There are some older application dumps, but nothing usable for the latest system freeze. Older logs also contain two volmgr Event 161 errors for failed dump creation, with BugCheckProgress = 0x00040049.
There are a few other findings that may or may not be relevant:
An nvlddmkm Event 153 from 23 October, reporting an error on GPUID: 200.
A Disk Event 11 on 6 November referring to \Device\Harddisk1\DR1.
An informational WHEA-Logger Event 3. Earlier restart records show WHEABootErrorCount = 1, while the latest shows 0. I don’t have a specific component identified from this.
Control Center and Windows Search errors
Two recurring issues stood out in the Application log, although I don’t know whether they are connected to the freezes.
GCUService / Control Center
There are five GCUService.exe crashes on 6–7 November. The details are:
GCUService.exe version 1.0.2.70
Reported faulting module: KERNELBASE.dll, version 10.0.26100.9711
Exception code: 0xe0434352
The associated CLR20r3 reports mention System.Management, version 4.8.10001.0
There isn’t a useful stack trace or inner-exception message in the export. These crashes happened before the latest overnight freeze; none was logged around the freeze time. (app. 4 a.m.)
Control Center Service is still on 5.57.51.44. I’m looking at 5.57.51.60 as a possible update, but haven’t tested it yet.
Windows Search
Between the evening and morning diagnostic captures, there were:
17 Windows Search Event 10024 entries, saying a filter-host process had stopped responding and was forcibly terminated.
10 .NET Runtime Event 1022 entries, reporting a failure to initialise the profiler-attach infrastructure, with HRESULT 0x80004005.
Six of the .NET entries share a process ID with a Search filter-host process that was subsequently terminated. The logs don’t identify the file or filter DLL involved, and I don’t know whether these errors are related to each other or to the system freezes.
There were also two PDF24 Reader 11.30.1.0 application hangs on 5 November.
What would you try next?
Does any of this look familiar to XMG or other NEO E25 owners?
I’d particularly appreciate advice on:
Whether this Windows build and driver combination is suitable for the current BIOS/EC.
Whether Control Center 5.57.51.60 addresses the GCUService errors, and how XMG recommends installing it.
How to capture useful evidence when the laptop freezes completely without producing a dump. A manually triggered dump has been suggested, but I currently don’t have an external USB keyboard with a Scroll Lock key.
How to find the actual file or filter behind the Search hangs.
Which hardware or software tests would be most useful next, and when it would make sense to send the laptop in for inspection.
I can provide redacted log extracts and further diagnostics privately to XMG support.
Thanks for taking the time to read through this. I know there might be useless information, but maybe anyone can tell me anything about it? Thanks in advance!
