Windows 10: Random lags

My laptop has the same problem with Windows 10 and Windows 11 24H2 after a clean install and update This happens regardless of the application, I've already experienced this problem with Edge and the Settings app, and it's probably happening with other apps as well Scrolling is the most laggy, with about 0.5 seconds of stuttering at random times The stuttering also happens when scrolling using the arrow keys or space bar on the keyboard, so it can't be a mouse problem The problem occurs randomly, sometimes it doesn't happen for a few days, and sometimes it happens once every few seconds s

Random Heavy Computer Lag

Hi Everyone! Was curious to know if I could get some assistance in helping me out with my studio machine. I'm noticing some very random very severe computer lag. I originally thought it could be a PSU issue, so I was able to under the warranty replace the unit and actually upgrade to a 1200 watt unit. I installed that, still had the issue and noticed some other graphical things going on ( Youtube Studdering, Heavy photoshop tools lagging down and not acting appropriately) so I swapped out my Nvidia GeForce 1080 cards running in SLI for a NVidia Quaddro RTX 4000 card. I'm still getting some random studder. Anyone have any suggestions? I know the machine can MORE than handle what I'm throwing at it so. Any 3rd party programs or Windows features that I can screen grab that someone can analyze for me? I checked the Windows Reliability feature through the control panel after I just had a severe lag and it turns out "SearchHost.exe" stopped interacting with windows at the time the lagging was happening so that led me down the rabbit hole of rebuilding the index, and then ultimately turning off "Windows Search". So I'll see what that does for me, but any and all suggestions is greatly appreciated so that I can continue back to getting some work done! Thanks!

 

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.
