My system has randomly been entering sleep while in use, and I am getting zero clues to why this is happening.

Here is the Details of the error

Although your laptop is a corporate-grade model, it is equipped with a high-performance processor that tends to run significantly hotter than others. The cooling system in the Precision 7520 was not designed to sustain maximum CPU and GPU loads for extended periods. The temperature is triggering a protective mechanism—implemented by either Dell or Intel—that puts the computer into a suspended state to prevent damage.

According to the Windows Event Log, the system suspensions were initiated by a driver process called WUDFHost.exe.

The HWiNFO log shows two interruptions occurring around 4:18 PM. Just prior to this, the CPU reached 95–96°C, and the GPU hit 92–93°C—the latter being its thermal limit (92°C). When the log resumes, HWiNFO explicitly indicates: “Thermal Event: Yes.”

Additionally, the "Intel Processor Thermal Subsystem" device fails to start during every system boot (error code 0xC0000365).

Based on this information, you can perform a few tests to verify the cause and attempt to resolve the issue:

  1. Access the Dell website below:

Be aware of ads that may advertise products frequently classified as PUPs (Potentially Unwanted Products). Please research any product advertised on the site before deciding to download and install it. 2. Click on Select Drivers Manually and download the Intel Chipset Device Software and Intel Dynamic Tuning Driver drivers.

  1. Install the downloaded drivers > Restart your computer > Check whether the computer goes into sleep mode while gaming.

    Thanks for the details! I noticed in the image that the "App Control for Business policy" is set to "Enforced." Is your computer a corporate device or managed by an organization?

    Try to determine if any process triggered the suspension while you were playing. Please send me the full Event log so I can analyze all the entries:

    1. Press WINDOWS + X > Select "Event Viewer" > Expand Windows Logs tab (Left Side).
    2. Right-click the "System" log > Save Events As > Put the log name of "System" and save it in an accessible place.

    Now upload this file to a cloud, such as OneDrive, and send me a link. Follow the steps below:

    1. Upload System Log in OneDrive. The link below shows how to do this. https://support.microsoft.com/en-us/office/carregar-fotos-e-arquivos-no-onedrive-b00ad3fe-6643-4b16-9212-de00ef02b586#:~:text=No%20site%20OneDrive%2Centre%20com,deseja%20carregar%20e%20escolha%20Abrir.
    2. When uploading, share the files via a link. In the tutorial below you have the steps explained.

    Hi!

    To help you investigate the issue, I need to ask a few questions and gather more information. Please answer the questions below and follow the requested steps:

    1. When exactly does the problem occur? For example, does it happen when the computer is idle, when you open a game or a resource-intensive app, or does it happen randomly? Knowing if there is a specific trigger helps in verifying whether a solution has worked by testing it against that trigger.
    2. Did the problem start after any hardware changes, a Windows or BIOS update, or the installation of a new program or game? Or did it just start happening out of the blue?
    3. Please provide the model of your computer. This will allow me to look for this specific issue on your particular device.
    • Press WINDOWS + R > Type msinfo32 > Press Enter > Send me a screenshot of the "System Summary" page.
