Windows 11 randomly freezes. No BSOD, no errors

My Windows 11 PC freezes randomly with no BSOD and no error messages. When it happens, the system becomes completely unresponsive, and I have to hold the power button to shut it down.

The freeze happens without any warning. I checked Event Viewer, but I can’t see any errors or critical events at the time of the freeze (for example, around 2:57 PM when it last happened). This issue started around 2 weeks ago. It mostly happens randomly during normal usage.

Before contacting here, I already tested the following:

  1. RAM:
    • Windows Memory Diagnostic → Passed
    • MemTest86 → Passed
  2. SSD:
    • CrystalDiskMark → Normal
    • Samsung Magician → No issues
  3. CPU & GPU:
    • Prime95 (CPU) and FurMark (GPU) running at the same time
    • I also monitored the 12V rail to check for voltage drops (it never went below 11.5V)
    • The system was completely stable during stress testing

My GPU and PSU are almost new (about 6 months old):

  • GPU: RTX 5070 Ti
  • PSU: Corsair RM1000x

Even after all these tests passing, Windows still freezes randomly during normal usage. At this point I am not sure what to do.

Hi,

What is the model of your motherboard?

Did you start having these problems after a Windows update?

Check if you have a minidump. Access the c:\windows\minidump folder, copy the files to your desktop, then upload them to OneDrive or Google Drive and post the link here for analysis.

Thanks

    It sounds like you're experiencing a frustrating issue with your Windows 11 PC freezing without any error messages or BSOD. Since you've already performed extensive testing on your RAM, SSD, CPU, and GPU without finding any issues, here are some additional troubleshooting steps you can consider:

    1. Check for Driver Updates: Ensure that all your device drivers, especially for the GPU and chipset, are up to date. Sometimes, outdated drivers can cause system instability.
    2. Run System Diagnostics: You can generate a System Diagnostics report by running perfmon /report in the command prompt as an administrator. This report may provide insights into any underlying issues.
    3. Event Viewer Logs: Although you mentioned not seeing errors in Event Viewer, double-check the System and Application logs for any warnings or errors that might not be labeled as critical. Look specifically around the time of the freezes.
    4. Check for Background Processes: Use Task Manager to monitor CPU, memory, and disk usage. High usage from background processes could lead to freezing.
    5. Perform a Clean Boot: This can help identify if a startup program or service is causing the issue. You can perform a clean boot by disabling all non-Microsoft services and startup items.
    6. Check for Malware: Run a full system scan using Windows Defender or another trusted antivirus program to rule out malware as a cause of the freezes.
    7. Power Settings: Ensure that your power settings are configured for maximum performance, especially if you are using a laptop. Sometimes, power-saving modes can lead to instability.
    8. Hardware Check: Since your GPU and PSU are relatively new, ensure that they are properly seated and that all connections are secure. Additionally, check for any overheating issues.

    If the problem persists after trying these steps, you may want to consider reaching out to Microsoft support or a professional technician for further assistance.

    Hello,

    I've found one possible solution and it's CR2032 sized little 3.0V lithium battery you need to replace with a new one on your motherboard.

    HTH,

    Mika

    You should consider the possibility that your PC may be compromised, and the freezing that you experience is the PC doing work for the attacker.
