Laptop Keeps Freezing

Based on the symptoms (hard freeze requiring power‑off, reproducible under specific load) and the Event Viewer screenshot, treat this as a Windows freeze rather than a normal app crash and collect more diagnostic data while narrowing down the cause.

Try the following steps in order:

1. Check whether the system is still reachable when frozen
   Next time the freeze occurs:
   • From another device on the same network, try to ping the laptop’s IP address.
   • If possible, try to connect via Remote Desktop or access \\<LaptopName>\c$ from another Windows PC.
   • On the frozen laptop, press Ctrl+Alt+Delete and see if the security screen appears.
     These checks help determine whether only the display/input stack is frozen or the whole OS is unresponsive.
2. Review logs after a freeze
   After rebooting from a freeze:
   • Open Event Viewer → Windows Logs → System and Application.
   • Look for Error or Critical events at the exact time of the freeze (Kernel‑Power 41 will just confirm the hard reset; focus on errors just before that).
   • Also generate a quick health snapshot by running perfmon /report from Run. This creates a System Diagnostics report that may highlight driver, disk, or resource issues.
3. Basic stability checks
   Since freezes occur with Rouvy + Netflix (GPU/decoder and network usage):
   • Ensure the latest graphics driver and network adapter driver from Acer’s support site are installed (not only via Windows Update).
   • Verify there is at least 10–15% free space on the system drive so Windows can create paging and temp files.
   • Temporarily test with one of the apps closed (Rouvy only, then Netflix only) to see if the freeze only happens when both are active.
4. Configure the system to capture a memory dump on freeze
   To properly diagnose, configure Windows to generate a complete memory dump when forced to crash:
   • Run sysdm.cpl → Advanced tab → Startup and Recovery – Settings.
   • Under Write debugging information, select Complete memory dump and enable Overwrite any existing file.
   • Ensure a paging file exists on the system drive and is at least RAM size + 100 MB, and that the drive has more free space than installed RAM.
   • In Registry Editor, create CrashOnCtrlScroll (DWORD = 1) under both:
     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters and
     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\kbdhid\Parameters.
   • Restart the laptop.
   When the next freeze occurs, hold the right Ctrl key and press Scroll Lock twice. This forces a bugcheck and writes %SystemRoot%\MEMORY.DMP. After reboot, that dump can be analyzed with Windows debugging tools or shared with support.
5. If freezes continue, collect performance data
   For deeper analysis while reproducing the issue:
   • Run an elevated Command Prompt and configure Performance Monitor logging as described in the documentation (using logman to start/stop a collection).
   • Let the log run while using Rouvy + Netflix until a freeze or heavy stutter occurs, then stop the log. The resulting data in C:\PERFLOGS can show CPU, GPU, disk, and driver behavior leading up to the freeze.

If, after these steps, freezes persist and dumps or logs point to hardware or a specific driver, contact Acer support with the collected MEMORY.DMP and Performance Monitor logs for targeted assistance.
