Issue with Driver_Power_State_Failure 0x9F Windows 11

Yesterday my pc started having issues, at seemingly random times it crashes with the error code being Driver_Power_State_Failure (0x9F).

It seems to be a problem with the SSD, everything is new, 4 month old pc. I noticed that it seems like the crashes happen when the SSD is very low use, like "sleep" state is what causes issues with the power management. Also, sometimes when it stays on for a while I get really weird issues, all of them happened just once, screen going black, some programs not starting at random...

A guide said it was probably driver issues, or windows update issues, but neither had problems and everything is on the latest version.

I tried to run the power troubleshooter, as a guide said, but the option just isn't there.

I tried to run the network troubleshooter but it got stuck in the middle and I couldn't use ethernet for a while (fixed later)

I opened the event viewer and found a lot of errors, but none seem to be really relevant.

I tried resetting Windows, but it still happens (it fixed the network issue tho)

I am going to try with a new install on a different SSD, just in case my Samsung one is dying, I will edit this once I'm done with it.

Can someone help me?

Please check to see if your PC is producing any minidump files, I will check those to see if they provide any insight into a potential cause of the system crashes.

Open Windows File Explorer.

Navigate to C:\Windows\Minidump

Copy any minidump files onto your Desktop, then zip those up.

Upload the zip file to the Cloud (OneDrive... etc.), then choose to share those and get a share link.

Then post the link here to the zip file, so I can take a look for you.

    The error code DRIVER_POWER_STATE_FAILURE (0x9F) indicates that a driver is in an inconsistent or invalid power state. Here are some steps you can take to troubleshoot this issue:

    1. Remove or Update Drivers: If you have recently added new device drivers or system services, try removing or updating them. Identify any recent changes that might have caused the error.
    2. Check Device Manager: Look in Device Manager for any devices marked with an exclamation point (!). Review the event log in the driver properties window for any faulting driver and consider updating it.
    3. Event Viewer: Check the system log in Event Viewer for additional error messages that might help pinpoint the device or driver causing the error. Look for critical errors that occurred around the same time as the blue screen.
    4. Power Options: Temporarily disable power saving features using the Power Options in Control Panel. Some driver issues can be related to system hibernation and power states.
    5. Hardware Compatibility: Ensure that any recently installed hardware is compatible with your version of Windows.

    If the power troubleshooter option is not available, you might need to check for Windows updates or consider reinstalling the drivers for your devices manually.

    Also, it may help to look at the minidump files from the crashes with a debugger.

    Can you zip up the minidump files in the C:\Windows\Minidump folder and make available (provide link) via OneDrive or similar site?

    If you have problems zipping the minidump files copy the minidump files to another location such as a folder on the Desktop
