It seems like you're experiencing a recurring issue with your PC freezing during demanding games, which can be quite frustrating. Here are some troubleshooting steps and considerations based on your description:
- Event Viewer Errors: You mentioned seeing nvlddmkm errors (Event IDs 14 and 153) in the Event Viewer. These errors are often related to the NVIDIA graphics driver. Since you've already tried reinstalling the driver, consider updating to the latest version available, as newer drivers may contain fixes for stability issues.
- Memory Dump Analysis: Since your PC freezes and you have to perform hard restarts, it might be beneficial to set up your system to generate a complete memory dump when it crashes. This can help in diagnosing the issue further. You can follow the steps outlined in the Microsoft documentation to enable memory dumps and analyze them later.
- Check System Resources: Monitor your system resources (CPU, GPU, RAM) while gaming using tools like Task Manager or Performance Monitor. This can help identify if your system is hitting resource limits when the freezes occur.
- Thermal Issues: Ensure that your GPU and CPU are not overheating. High temperatures can lead to system instability. Check the temperatures while gaming and consider cleaning your PC or improving airflow if necessary.
- Power Supply: Your PSU is rated at 750W, which should be sufficient for your setup. However, if it is failing or not delivering stable power, it could cause crashes under load. If possible, test with another PSU to rule this out.
- BIOS Settings: Since you reset your BIOS to default settings, ensure that any overclocking settings are disabled. Sometimes, aggressive settings can lead to instability.
- Hardware Acceleration: You mentioned turning off hardware acceleration in many applications. Make sure this setting is consistent across all applications, especially those that might run in the background while gaming.
- Windows Updates: Ensure that your Windows installation is up to date, as updates can include important fixes for performance and stability.
- Additional Testing: If the issue persists, consider testing your RAM with tools like MemTest86 to rule out memory issues, even if Windows Memory Diagnostic did not report errors.
- Game Settings: Since the issue seems to occur more frequently with demanding games, try lowering the graphics settings to see if that alleviates the freezing. This can help determine if the problem is related to GPU load.
If the problem continues after trying these steps, you may want to consider reaching out to a professional technician for further diagnostics, as it could be a more complex hardware issue.
