windows blue screen - DPC watchdog violation
« on: January 28, 2022, 08:18:37 am »
When turning pc on, it just freeze at login screen after few seconds.
I though its ssd disk and run sfc/ scannnow or chkmdsk  /f /r
It works for once. Second day it just freezed again on loging screen. I did factory reset. Again it works.
Today it just freezed. So i guess i will reinstall windows and block windows updates.
Its pain in the ass. Any health check software reccomendantions?

One thing that causes this is a lot of mapped network drives that can no longer be resolved.  It may appear to lock up with a blank screen after login for up to several minutes as it tries to reconnect to each of the missing drives.  Could be worth checking that if you haven't already.

Ok i have found out that laptop freeze when try to connect to 2.4 Ghz wifi. Wifi adapter is RTL8852AE.
5GHz works fine. 
I need to know if wifi card is OK and drivers are bad. What should i do? Does wifi works on linux live cd?

It depends on which one in particular but Linux drivers are available for it:

You're correct
RTL8852AE has bad reputation esp. in 2.4 GHz, seems aimed more on 5GHz.
It's wifi card not of drivers

Do you think I can switch wifi card to ax 200? I am able to find only this desktop kit.
