Hardware causing lag in windows.

Recommended Posts


I am running windows 11 but it was doing it on windows 10.

When I leave the PC for a day or two when I come back to it it does not work properly. It drags.. You move the mouse and you can just wait for it. It is like I am out of ram. A restart fixes it.

I have run two different memory tests. I thought that was going to be the problem.

I checked for viruses and spyware using two different programs. 

My CPU usage is normal.

Memory is at 16 percent

The device manager is clean.

CPU temp is perfect

I have checked the disk and it is fine.

What am I missing?

You don't give a lot of information about the system. I got a new PC with AMD Ryzen 7. I was on W10 (latest upgrade). I moved to W11 and found the PC to be faster, especially power on/off. I had 16G memory but a friend had purchased an 8G card by mistake so I bought that, but did not notice a difference. I cleared out a load of MS crap I would never use. Did a complete spring clean off system files & storage after the upgrade as well.


I had been using a Logitech MK270M185 combo, a very reliable workhorse for input. With W11 I noticed keyboard stutter and the mouse sleeping and, yes, I had noticed something similar recently on Win 10. I put this down to being on the 21H upgrade. I spent many hours checking online advice, trying to get new drivers, etc. Nothing worked. I eventually decided to buy a new combo. That is a minefield, especially as I key at night and wanted a backlit board. Anyway, I have a new board/mouse and everything is working fine. I checked the drivers and they still use the HID compliant MS drivers, and they date from 2006! I guess if it works then why would firms change it? Or, are they too lazy to to create their own?

Perhaps if you could borrow a combo that is another make, preferably new, and test? Mind you, the way the world works today the innards are ancient and the outers are cutting edge eye candy!


Be aware of this from Microsoft:

WIN 10 20H2


You don't say what programs you use for test/clean. There are so many on the market doing slightly different things. A lot of them are dreadful.

CCleaner is pretty good, but add the enhancer. Use it to clear out the cookie cache, but remember to let it keep those cookies you need. People prefer other programs to this. Just personal preference.

I loved TUT - The Ultimate Troubleshooter, but it is long gone now and others do better jobs, perhaps. But I liked the way that info was given for each process and explanations why to consider options for keep/amend/delete rather than just clean regardless.


I guess this could lead to a general chat about what folks would recommend for housekeeping, but I think that should be in another topic.

Try to perform a clean boot in Windows

A “clean boot” starts Windows with a minimal set of drivers and start-up programs, so that you can determine whether a background program is interfering.  This is similar to starting Windows in Safe Mode but provides you more control over which services and programs run at start-up to help you isolate the cause of a problem.    

  1. In Windows 10, in the search box on the taskbar, type msconfig. 
  2. On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
  3. On the Start-up tab of System Configuration, select Open Task Manager.
  4. Under Start-up in Task Manager, for each start-up item, select the item and then select Disable.
  5. Close Task Manager.
  6. On the Start-up tab of System Configuration, select OK.  
  7. Restart the computer, it's in a clean boot environment.

If your problem does not occur while the computer is in a clean boot environment, then you can determine which start-up application or service is causing the problem by systematically turning them on or off and restarting the computer.  

  1. While turning on a single service or start-up item and rebooting each time will eventually find the problematic service or application, the most efficient way to do this is to test half of them at a time, thus eliminating half of the items as the potential cause with each reboot of the computer.  
  2. You can then repeat this process until you've isolated the problem. 

Reset the computer to start normally after clean boot troubleshooting after you finish troubleshooting, follow these steps to reset the computer to start normally.

  1. In Windows 10, in the search box on the taskbar, type msconfig. 
  2. Select msconfig or System Configuration from the search results.
  3. On the General tab, select Normal Start-up.
  4. Select Services, clear the check box beside Hide all Microsoft services, and then select Enable all.
  5. Select Start-up, and then select Open Task Manager.
  6. In Task Manager, enable all of your start-up programs, and then select OK.
  7. When you're prompted to restart the computer, select Restart.

Hard Drive failure is imminent

Most components on a PC that can fail will give some warning of their deteriorating condition before they just stop working altogether, and hard drives are no exception.

Here are some warning signs of a developing hard drive problem:

  1. Disappearing files: If a file simply disappears from your system, this can be a sign that the hard drive is developing issues.
  2. Computer freezing: Computer freeze up from time to time, and it’s almost always solved by a quick reboot. However, if you find that you need to reboot more and more frequently, that could be an indication that your hard drive is beginning to fail.
  3. Corrupted data: If files on the drive are suddenly corrupted or unreadable for no apparent reason, it’s possible that your hard drive is experiencing a gradual failure.
  4. Bad sectors: If you start receiving error messages about “bad sectors”, “CRC” or “Cyclic Redundancy Error”, that is a sure sign that your drive is developing problems.
  5. Sounds: If your hard drive is making sounds that you aren’t familiar with, this could also be bad news, particularly if it’s a grinding, clicking or screeching noise.

MMT, thank you very much for your response.  I am embarrassed about how long I have been using CCleaner.  I have also tried Malwarebytes and SPYBOT. I checked for viruses and the system is clean. 


UK666-- Thank you for reminding me I'm in my upper 50's. Yes, that is exactly what I need to do. How I have not done that yet is crazy. I checked running and resources but didn't go all the way.  Boy am I glad none of my buddies know about this post.
