Once it freezes, I can't move my mouse pointer or keyboard. Only to hard shutdown my PC.
I did not update my drivers. Nothing is shown to windows update settings window. My PC is Dell Inspiron 15 3552.
Driver name: Qualcomm QCA9565 802.11b/g/n
Driver date: April 21, 2017
This just happens randomly. It also occurred on my old laptop (eME528)
Somewhere in the driver, I just turned off the checkbox "Turn off this device while the computer is on sleep" and now, My PC is functioning properly again. No more freezes.
