Hi @Emte89 welcome to this free user to user Alienware laptop discussion forum. 

Support for Dell G15 5515 Ryzen Edition provides Drivers & Downloads for Windows 10, 64-bit and Windows 11. Hopefully the fix will be the same for both operating systems. 

Please run windows Reliability Monitor and wait for creation of event timeline. Open event for DRIVER_POWER_STATE_FAILURE to see root cause of blue screen. There should be a Microsoft error code. How to use Windows Reliability Monitor to identify software issues

Driver Power State Failure errors are usually caused by a computer or device driver going into sleep mode while you’re still using the device. Windows will send a wake signal to the device once it is needed and if the device doesn’t respond in time or at all, Windows flags a Driver Power State Failure error. The error can be caused either by the driver itself or power settings. Two popular causes of this error are graphics drivers and internet card drivers. Please go to Device Manager and in Power Management tab and disable option 'Allow the computer to turn off this device to save power'. 

Ofcourse i have latest drivers from support dell app,

I ticked off the network card like in your screenshot.

I run windows Reliability Monitor and i have so many errors:

Hi @Emte89 thank you for sharing additional information. Unfortunately this Alienware Laptop forum is for English user to user discussion. Not sure what Reliability Monitor is saying, Translation of BlueScreen event from Polish into English gives:-

Which reiterates Driver Power State Failure error. Please use Intel® Driver & Support Assistant to identify your products and get driver and software updates for most of your Intel hardware. This includes graphics drivers and internet card drivers. Thank you. 

I install Intel® Driver & Support Assistant and update 2 drivers - bluetooth and internet card.
Maybe it's help, 2 hours ago I had BSOD again so the previous steps did not help

Hi @Emte89 thank you for sharing update. 

Having updated graphics drivers and internet card drivers followed by Restart (not Shut Down) to save changes, please revisit Device Manager and in Power Management tab, disable option 'Allow the computer to turn off this device to save power'. 

[SOLVED] BSOD: Driver power state failure ntoskrnl.exe - Microsoft Community 

Please upload any minidump files you have, 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, DropBox... etc.), then choose to share those and get a share link.

hi guys,

I just made an account to share my solution with you that I finally found for my Dell Inspirion 5515.
After a long way of misery: Where I had bluescreens again and again and especially when waking my dell up from hybernation or energy saving mode, I finally found the problematic driver:

DisplayLink Graphics Version
I deinstalled my current version 10.3, restartet, and installed the version 11.0 from the official website:
https://www.synaptics.com/products/displaylink-graphics/downloads/windows

And now it finally works and nothing is crashing anymore... At least so far... If you don't hear from me it is still working. Fingers crossed

hope I could help, life is too short for bluescreens.

Hi guys! So the DisplayLink Driver was not the Problem... I still had several bluescreens in the past 9 months lol, always from ntoskernel.exe
For me, it was the SupportAssist that may had problems with the drivers windows 10 installed via windows update.
I made myself an windows 10 usb Stick with the known tool from microsoft and booted from it and made the whole windows new...several times actually to find out what the problem was. So:
I am pretty sure, that the problem was updating the drivers via the dell update tool or with the SupportAssist. Something does not work properly there. I just did all the updates windows 10 had for me, also including the optional driver updates.
So far I am running without any bluescreens! I hope it stays like that :)

Hey, I have similar problems, usually only after i turn on my laptop and I am trying to use some GPU-demanding app then randomly (30% of time?) I will get a crash with BSOD with text about "DRIVER_POWER_STATE_FAILURE". I am using dual-boot and when I was using nvidia GPU on my Linux it was working without any problems.

Could you help? Updating drivers is helping only until Microsoft is not shipping next updates... or it is just random.
