My computer while browsing firefox randomly had the screen go black and the fans started spinning very loudly

Hello NaoiseR, I'm Quinn, and I'm happy to help.

The Event Viewer log indicates that your Desktop Window Manager (dwm.exe) crashed due to an error in its core module (dwmcore.dll). This is a common Windows error that can cause visual glitches, screen flickering, or even a complete desktop crash. Here's a breakdown of the information provided. Faulting application name: dwm.exe (Desktop Window Manager). Faulting module name: dwmcore.dll (Core module of DWM). Exception code: 0x8898008d (This is a generic error code for DWM crashes)

Possible Causes of these are:

-Outdated or incompatible graphics drivers: DWM relies heavily on your graphics drivers, so outdated or incompatible versions can trigger errors.

-Corrupted system files: Issues with system files can affect how DWM operates.

Software conflicts: Certain applications or background processes might conflict with DWM.

-Hardware issues: Less commonly, faulty hardware components (like your graphics card or RAM) can sometimes lead to DWM crashes.

Troubleshooting Steps:

-Update Graphics Drivers: Download and install the latest graphics drivers for your system from the manufacturer's website (e.g., NVIDIA, AMD, or Intel).

-Check for Windows Updates: Ensure your Windows installation is up-to-date. Microsoft often releases patches to fix DWM-related issues.

-Run System File Checker (SFC): Open Command Prompt as an administrator and run the following command: "sfc /scannow". This will scan and repair any corrupted system files.

Please try these steps, and let me know if you need further assistance.

I see, based on the picture you gave is your BIOS is reporting "CPU Fan speed detection error". Double-check that the CPU fan's power cable is firmly plugged into the CPU_FAN header on the motherboard and gently wiggle it to ensure a secure connection. Also, verify that the fan itself is correctly mounted on the CPU and that there's no obstruction hindering its free rotation. If you're confident adjusting BIOS settings, enter the BIOS setup by pressing the F1 key, navigate to the "Monitor" or "Hardware Monitor" section, and try lowering the "CPU Fan Speed Lower Limit" to 200 RPM or setting it to "Ignore". Keep me updated on your progress and don't hesitate to ask if you need further help.

Hello

I did what you said and it did work and fixed all the corrupted files but a few hours later my pc screen went black again although this time the fans did not go to 100% speed and when I rebooted I got a bios error, sadly I couldnt take a picture fast enough but it said something about CPU fan speed detection error

This is not my error but a picture I found online which I am pretty sure was the same error

The log shows numerous instances where the hashes (checksums) of system files don't match the expected values. This suggests that the files have been modified or corrupted. Use DISM to check the health of the component store and restore missing or corrupted files. Open Command Prompt as administrator.

Type "DISM /Online /Cleanup-Image /RestoreHealth" and press Enter.

After DISM finishes, you can optionally run "sfc /scannow" again to see if it can now fix the remaining files that it couldn't repair earlier.

Please let me know how things turn out. I'm here to help if you have more questions or need additional support.

Hello thank you for your advice

I have updated my graphics drivers and checked for updates

I ran that command but it gave me this error could you give me some more advice?
