Windows 10: Windows freezes for 30 seconds and then goes into a BSOD

I've been having this problem for a while now, and I really can't tell what is wrong with my computer.The first boot up of my computer of the day, I log in, a couple minutes later, freezes and BSOD, after the reboot, it doesn't happen again.I have no clue what is the problem, maybe because I have a Lenovo prebuilt.Please help ASAP.

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.

 

Log in/Sign in every 30 seconds

Hi,

One of the possible cause, why your laptop asks you to re-log in, is because of the current power option set on your system.

Can you tell us if your laptop goes into sleep mode after 30 seconds?

If so, kindly follow the steps to further isolate the root cause of this issue.

• Type Power & sleep in the search bar, then click on it.
• Check if your current power option is set for your device to go into sleep mode after 1 minute.
• Change it to never and see if the issue will occur.

Let us know how it goes so that we can further assist you.

 

BSOD and freezing

Yesterday I started up my laptop from hibernating and it freezes, after restarting several times I get a BSOD which freezed on the BSOD one time.
After restarting again the laptop freezed at the Welcome screen.
I have had the freezing before, it was gone for about 2 months.
I did not install any new hardware.
Now it seems to run fine again.

But what is causing the freezing and the BSOD?
I bought this laptop last January.
