Random lag spikes

Hi,

We would like to know more about your lag issue:

• What browser are you using when you experience a lag?
• Does the lag occur in a particular game?

In the meantime, we suggest you run the System Maintenance troubleshooter. Here are the steps:

• Press Windows Key + X.
• Click on Control Panel.
• Select Troubleshooting.
• On the left pane, click on View All.
• Click on System Maintenance to run the troubleshooter.

Looking forward to your response.

 

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.

 

random restarts

Hi,

If a Windows computer random restarts, the device usually have some damaged system components. For us to provide an accurate solution, we would need you to answer the following questions:

• Which build, version and edition of Windows is installed on your computer?
• What changes have you made to the device before this issue occurred?
• What troubleshooting steps was already performed to your laptop?

In the meantime, it will be best to make sure that the latest update of Windows is installed on your device. If the same issue happens after installing Windows Update, we suggest running the power troubleshooter. To do so, follow these steps:

• Open the Control Panel.
• Using the search bar at the upper-right corner, type troubleshooting.
• From the search results, click on Troubleshooting and then select System and Security.
  
• Click on Power and then follow the prompts to successfully run the tool.

We are looking forward to your response.
