New PC slower and full of lags

Process Monitor and Process Explorer should have clues as to the cause. The devil is in the details.

You can try Winder Performance Analyzer. I am reluctant to throw that one out there because it has the widest learning curve but it is a great tool for performance tracking. It has since moved into the Windows Store: https://www.microsoft.com/en-us/p/windows-perfo...

And a video guide can be found here: https://docs.microsoft.com/en-us/windows-hardwa...

Just an idea, but have you tried starting from a portable Linux build? Just to see if the issue is software or hardware related?

Hi, WilliamDZ,

thank you for offering all those help tips and I went through all of them once again, with accents on the ones you mentioned:

• EVENT VIEWER lists no special warnings or errors, which would be performance-related. All warinings I see a lot on client's computers (I am service technician, too) and most of those can be safely ignored, according to MS.
• My STARTUP PROGRMAS list is quite short, especially compared to my OFFICE PC and to my OLD PC. On botrh mentioned other computers I have, beside those apps, I have on my NEW PC, also Hyper-V virtualization and Veeam B&R console, plus ESET Remote Admin and IIS + PHP + MySQL testing web sites. So my NEW PC is really not geared up (yet) and it should run smoothly.
• All performance tools, Task Manager, Performance Monitor and also Samsung Magician show CPU scratching the bottom most of the time, disk writes graph up to 100KB/s, like nothing, really a bunch of free resources to use.
• Tried to unload Antivirus (ESET NOD32), backup tools, and uninstalled Skype, all those X-box **** (sorry MS, but I still do not understand why X-Box on office or workhorse computer...we are not playing games), disabled almost all unnecessary startp items...but at no avail, all is laggy.
• Also tried to use USB wired mouse instead of Logitech M720 Marathon wireless...but same lags again.

What I suspect is GRAPHICS driver issues.

Because even when I resize benign apps on screen, whic do not need to re-render content (like MS Paint or Picture viewer), those mouse-dragged windows resizing is laggy, way from smooth.

I've also gone to BIOS and MAXED out both DVMT settings for video ram allocation, but that did not make any difference.

Very weird is that all opened windows got resized to****860x770px after each and every SLEEP period, where only display goes to sleep, not the PC! Sleep, disk sleep and hybernate are all turned OFF. What's more weird, resized are only WINDOWS, NOT DESKTOP! I mean, after waking up the display from sleep, all windows are smaller, but icons on display are still aranged all over the full screen, exactly like I left them before.

I have screen size set to native monitor's 2540x1440 and text scaling to 100%.

I also have proper DISPLAY DRIVER for AOC monitor Q3279WG5B.

Ufff...still looking for help

Hi and thanks for reaching out. My name is William. I'm a Windows technical expert. I'll be happy to help you out today.

There is no easy answer to this. You need to employ some investigative skills. To start, try to identify the source of the bottleneck(s) using build in performance and process tools.

Parse the Event Viewer, specifically Applications and Services. I tend to focus on warnings and errors, but spotting the ones that are responsible for performance issues can be a bit challenging with all the "noise" in the Event Viewer. There is just so much happening and much of it is benign.

Use Task Manager. I assume you have already been over processor metrics and did not identify anything specifically consuming CPU cycles. However, if you have not, use Resource Monitor to view CPU usage on the individual cores for periodic but consistent spikes. In my work environment, i use to see this a lot and the normal TM will not catch those brief spikes.

Do not neglect the other aspects of resource contention: RAM, disk, and network IO usage. More often than not, mysterious performance issues for me manifested in disk queue filling up, and modern SSDs have not negated that still being a bottleneck. In TM and RM you can add additional columns of information. I tend to focus on excessive writes and also add Threads column to the Details tab in TM. I recently came across an issue with our enterprise security software that was bogging done some workstations because the number of threads from the responsible process had climbed into the millions but you would have never known as CPU performance was not indicating usage. Anything more than 100k threads can be considered a performance hindrance.

Also look at your startup programs list. This can be found in TM > Startup tab.

Another built in tool I have used is Performance Monitor. This has a bit of a learning curve but its not too terribly advanced. There are dozens of useful counters you can add. Again, I tend to focus on disk queue. This is a good read: https://www.sciencedirect.com/topics/computer-s....

Other tools I use are Process Explorer from Sysinternals (now Microsoft) to look into process details. This is like TM on steroids.

Process Monitor, also from Sysinternals. This logs every operation imaginable on your computer. Capture a trace for a minute or so and try to build a profile using the various filters and isolate system resource usage to individual processes. Note, this can be a built overwhelming to use at first. I have many case examples on my blog: www.windowsexplored.com.

Autoruns. Yep, Sysinternals again. Examine in minute detail every program, process, module and component that is loaded on start up and logon.
