That's a issue with your PC not Steam. Without knowing your PC specs in full (including all hardware installed), it will be very hard for anyone to help you.

it started happening after a windows update that took 30min to update my laptop is lenovo ideapad gaming 3
gpu: gtx 1650
cpu: AMD Ryzen 5 5600H
if you need any more specs tell me

Disable HW acceleration for web views and restart Steam. Report results.

its already disabled

find blue screen crash report and look what caused it, it mentions there what happened and what caused it

this is what i get: The mbamchameleon service failed to start due to the following error:
The system cannot find the file specified.

"The genuine MbamChameleon.sys file is a software component of Malwarebytes Chameleon by Malwarebyte." Something could be wrong with your install of Malwarebytes.

If you do not have malwarebytes installed, or have uninstalled it recently. There may be leftover files or the uninstall was not completed successfully.

Hopefully this helps you find a solution.

i did it but now it says a new error: The previous system shutdown at 2:55:57 PM on ‎10/‎6/‎2025 was unexpected. even though i can just close steam and open the game i want to play its still a bit annoying that it does that

update: i know cant open any steam game even with steam closed it still blue screens

So when i open a steam game with steam opened it "blue screens" but its black screen with the sound that the blue screen does, but when i open a game without having steam open it logs me in steam and opens the game like normal. I hope someone can help me fix this

so now i fixed it i think after fixing the .sys file i needed to only DELETE STEAM CACHE. Cant believe it was so simple i hope its fixed forever. Thanks for everyone who helped me by replying
