Mouse and Keyboard not registering clicks. Random Slowness.

[sata67]

During standard computer usage such as internet browsing, and file management in Windows Explorer, I experience things like:

-Mouse not registering a click during browsing (I click again, and it works).

-Keyboard sometimes missing clicks as well. This can be a single key/letter, or not responding when trying to paste text (Ctrl+V). This only happens in certain scenarios, and not in others. This does not happen if I am writing in a Notepad file. But this will happen if I am writing the same post directly in a forum text box, which included more fancy rich text features.

-Using Windows Explorer, dragging a video file to a madia player will feel sluggish for a second. The mouse does not move smooth. But the video plays fine.

-While trying to select multiple files (Also in Details View), sometimes it will feel sluggish for a secnod.

-While playing games, the run fine and smooth, but frames will drop for a couple of seconds / stutter, immediately after a loading sequence.

-My monitor (which is 144Hz) will drop to a much slower refresh rate (not while gaming), if I hover my mouse over specific Programs / Apps. I switch to another program, or to the desktop, etc, and it returns to 144hz (I see the frames from the OSD, and also notice the mouse movement is much more sluggish).

-One problem, which happens now, and alsoo happened before the new windows installation, seems like it is a bug / Windows related, which puzzles me. It is like a bug that happens when I am having several Windows Explorer windows and going from one to the other using the taskbar. I can't explain it but I can try and capture it if it will help.

I described as best as I can some of the problems I experience. These happen for a couple of months now.


Things I have tried until now:

-Running MemTest86. Passed with no errors.

-Using different mouse and keyboard (both wired). As well as connecting them to different USB ports.

-Fresh installation of Windows 10. And then installing the necessary drivers. At first, some of the problems seemed better, but after a couple of days they now happen again. And it seems a bit worse.

-Turning off the computer and cleaning from dust. Then checking all the cables are connected properly:

After I tried to turn on my computer, it would turn on, then off after 1 second, like a loop. I turned it off again. The next morning I turned it on and it powered on fine.
Because of that, I thought maybe it is a faulty PSU. But I also noticed this area on the motherboard, which looked like its fried..?

And here is a picture which I took 5 years ago, just after I put together my computer:

I should mention I use a UPS (uninterruptible power supply).

Well a couple observations.

First - kudos to you for using an UPS. IMO, every computer should be on a good UPS with AVR. That said, I don't see how an UPS could cause your problem. However, you could always bypass it just for a test to eliminate that from the equation. That does not eliminate power as a possible problem, but more on that later.

You said you already re-installed Windows. And according to the Zowie webpage, no drivers are used for that mouse. But you tried a different mouse and keyboard so that eliminates them regardless.

I find it odd you want to suspect Windows, but suggested it worked fine potentially for years, then the problem started, and the problem remained after re-installing Windows. That would suggest to me something else you installed that is running in Windows, not Windows itself. What security programs are you using? What other programs run with Windows?

You tried different USB ports - that's good, except it didn't fix your problem.

If these were a wireless keyboard and mouse, I would suggest looking at possible EMI/RFI issues from other nearby electronic sources. While interference can still affect wired devices, it is less likely. However, I would still check your wall outlet. Every home and every computer user should have access to a AC Outlet Tester to ensure the wall outlet is properly wired and grounded to Earth ground. I recommend one with a GFCI (ground fault circuit interrupt) indicator as it can be used to test bathroom and kitchen outlets (outlets near water) too. These testers can be found for your type and voltage outlet, foreign or domestic, (like this one for the UK) at most home improvement stores, or even the electrical department at Wal-Mart. Use it to test all the outlets in the home and if a fault is shown, have it fixed by a qualified electrician.

If your outlets is good, then I am back to power. I would swap in another known good PSU to see what happens. Since everything inside the computer case depends on good, clean, stable power, you need to verify you are delivering it. And if the problem remains with a second PSU, then I might start suspecting your motherboard.

Yes, my computer worked properly for years, until a few months ago.

After I did a fresh Windows install, I first installed some drivers for my Sound Card, GPU. I think Windows handled some of the more basic stuff like Motherboard drivers or whatever is needed for basic functionality.
Windows Update also did its thing with important Windows updates or hotfixes.

I will list some of the programs I installed: Firefox, Chrome, EVGA Precision, Discord, COMODO Free Firewall+Antivirus, Corsair LINK (Software that shows information about the PSU - I will take a screenshot if that will give any useful information).

I can look through the rest, but honestly I don't think I installed anything unique that could affect on such thing... I only installed some basic programs like browser and the programs/apps I use.

My KB+Mouse are wired, and I have tried different Wired KB+Mouse ones. The same behavior happened.

Regarding the PSU - I will see if I can replace it in order see if that will solve the problem. I will see if the one from another PC will suit this one.

Regarding the Wall outlet - I will get on checking that as well as soon as I can.


And I am thinking a bit forward here: If it will turn out to be a faulty Motherboard, I will be in a bit of a problem. Since these motherboards are not available for purchase anymore. That will mean I will have to get a new Motherboard as well as CPU. I don't even use my computer for gaming much, I just want it to do the basic stuff at this point, heh.

I will get on checking the things you mentioned, and hope to have an update sometime soon!

So I brought in a different Desktop PC (As well as a monitor) from my family's house.
It is maybe 1 year old and with newer hardware.
It also has Windows 10 installed on it.

I connected it to a different power outlet, in a different room than my main computer.

So I've been using it for a few hours just to see if I experience similar behavior like in my computer.

So writing in a forum with rich text features features - the same thing happens. I can't paste or delete. And I do not think that is how it is supposed be... Then switching to non-rich text mode, it works fine.

I also tried this: selecting multiple files by dragging and highlighting them with my mouse. This behavior happens, in *both* Computers (Video):

https://imgur.com/a/sxbKBdG

It takes maybe 15 seconds until all are selected, and until it fnishes, I do not have control on that window.

If I change the taskbar location from bottom of the screen, to the right of the screen (in windows settings) - the save thing happen as you see in the video, but the selection window might go even slower, and it takes maybe 25 seconds to highlight them all.

And if I click on the top file and then shift+down with my keyboard- it selects them all immediately.


So, I don't think these weird bugs are normal? I tested it on 2 different computers in my house.

So maybe something's up with the power to my house (?)


Another thing I should mention: When I powered on my 2nd PC for testing, I had to reset the Windows log-in password.
Each of my PCs have genuine Windows keys, but both are connected to the same e-mail (so when I reset my password to one PC, the password also resets to the other PC).
I just mention it because after I reset my password, then in my main PC, some bugs changed...
For example, in this video I posted in my thread a few days ago, the monitors refresh rate will now not drop while hovering my mouse over that window. It *will* drop only while dragging that window. So bizzare.

So maybe it has something to do with Windows e-mail or activation settings?

I'm by no means an expert, but if I had to guess, I would say some component(s) on the motherboard are going. You might want to post your system specs, too, and how long you've had it. Win 10 could be causing problems, too, depending on how old the system is. Just a guess.

Hi, thanks for the reply

At first that what I was thinking as well, but now I'm not entirely sure.

I have listen my system specs - they are just below my avatar. If anything is missing let me know.

My windows installation was 4 years old, but I have already did a fresh install and the bugs are still there.

All of my endeavors so far are in this thread

The part of the motherboard that you're saying looks fried is the heatsink. As for what is underneath and what might be fried, I couldn't tell you. But I'm pretty sure the motherboard manual is still available for downloading: https://us.msi.com/Motherboard/Z270-GAMING-M5/support#down-manual so you'll be able to check here.

 

[sata67]

Well it took a while but I finally got around to trying to solve it

I took a newer PC build, and changed my SSDs from the computer which I experienced the problem, to the new one.

So now I have my: GPU, Sound Card, 2 SSDs, 1 M.2 SSD (OS) moved to a new computer, with a newer Motherboard and CPU generation.


And... the problems still exist.

I have no idea what else I can check?

Please disable global c-state option in bios

 

[bug]

Fire up resource monitor, see whether there's unusual activity when you experience the slowdowns. Could be a rogue AV, a keylogger or something...

 

[sata67]

I disabled it (it was set to Auto)
I still experience these issues. I have the mouse lag thing when certain windows / apps are focused.

My new hardware btw:
Motherboard changed from MSI Z270 to Z390-A Pro
CPU changed from Intel 7700K to i5-9600KF

-My monitor (which is 144Hz) will drop to a much slower refresh rate (not while gaming), if I hover my mouse over specific Programs / Apps. I switch to another program, or to the desktop, etc, and it returns to 144hz (I see the frames from the OSD, and also notice the mouse movement is much more sluggish).

Set G-Sync to "Enable G-Sync for fullscreen mode" in Nvidia driver settings.

I opened it, as well as task manager.

Whenever I am focused on WhatsApp app, my mouse lags and the monitor's refresh rate drops from 144 to about 50. Also, the whatsapp processes CPU usage goes up from 1% to 3%. After 5 seconds the lag is gone and CPU drops back to 1%.

The same mouse lag happens with COMODO Firewall, but only the lag. There is no CPU or memory movement

Set G-Sync to "Enable G-Sync for fullscreen mode" in Nvidia driver settings.

I just tried that now. It was enabled for both fullscreen and windows mode. Nothing has changed though. There is still mouse lag.

I disabled it, and that seems to did the trick for the mouse lag. But why does this happen? it did not before.
EDIT: tried to restart, and set to fullscreen only (no windowd mode), and now there is no mouse lag.

Also, I still have the weird copy and paste issue I described some posts above. That did not fix this.

My guess is that it has something to do with monitor going in and out of the g-sync range, which is 35-144(165).

As of the other issues - get rid of that COMODO antivirus/firewall and use built in Windows Defender instead, see if this helps.

Look for disk or network spikes if nothing's hogging the CPU.
