I have 2 devices, a PC and a laptop. This PC has been having a really weird issue with my mouse and keyboard. They both just don't register my inputs sometimes. Sometimes they're stuck to my last input. This does not happen with my laptop. I am confused on what to replace to fix said issue because I don't have a spare to test it. I myself am pointing my finger toward either the motherboard or the PSU.
  • Ryzen 5 5600G
  • Palit RTX 3070 GamingPro
  • ASRock B450M Steel Legend
  • PNY XLR8 EPIC-X 3200Mhz DDR4 (32GB - 16x2)
  • ADATA XPG Spectrix S40G (1TB)
  • Fractal Design Ion+ 2 Platinum (660W)
Above is the specs of my PC. I hope someone could give me clarity on which part of the PC is at fault and should I replace.

Note: Both mouse and keyboard have issues on both 2.4Ghz and wired.

Not trying to be "that guy" but... have you tried replacing the battery with fresh new ones?

I'm being serious. One time my Logitech mouse began acting erratically while playing Destiny 2 (and only D2) with random misclicks and dropouts... I reinstalled all kinds of drivers, the game, some Ease of Access settings, and even some random BIOS settings (because I thought the USB ports might be dying) and even replacing the PSU (I was getting desperate), and nothing worked... The mouse was still problematic.

I switched the batteries and... everything worked once more. I know it's such a small thing but worth a try..

Although blue tooth is really robust where is your desktop tower located.

Maybe you have a dead zone. Only reason maybe to check is it effects both mouse and keyboard.

Could be also drivers mentioned from ex_bubblehead .Bot​

Both devices use 2.4 Ghz, but this happens with both 2.4 and wired as I usually just use them wired and the issue persists.

Not applicable. Both devices have built in battery, and I usually just used them with cables so battery shouldn't be an issue. Different mice (both wired and wireless (2.4 Ghz and wired)) all are also having the same issue only on the PC, not the laptop.

List all other peripherals being used by the host computer.

Have you tried the keyboard and mouse on another known working computer?

Have you tried other known working keyboards and mice (wired and wireless) on your computer?

Have you looked in Reliability History/Monitor and Event Viewer for any error codes, warnings, or even informational events being captured just before or at the time of the failures?

Check Task Manager and Task Scheduler for any unknown or unexpected apps or utilities being launched at startup or later being triggered by some other action on the computer.

How old is the PC's PSU? Original to build, new, refurbished, used?

The computer used to power a really cheap ring light during nighttime, hence why I was suspicious the motherboard's USB controller is at fault. Other peripherals being a USB microphone (Fantech Leviosa MCX01), this exact mic is also used a lot recently with my laptop and no issue popped up.

The exact keyboard-mouse combo was used on my own laptop and my mom's. Both seem to have no issue at all.

I have multiple wired and wireless mouse, not keyboard, and yes I have tried them and they all seem to have the same issue on said PC.

I have looked in Event Viewer but after a few searches with Google none seem to be related to the mouse and keyboard issue. However, since I started noticing the issue when I was playing a game, I do notice something different in Event Viewer while playing the game on my PC and my laptop, although after a few searches seem to point to Easy AntiCheat. Easy AntiCheat does not seem to be an issue as this happen at random even while just opening Edge, and it still happen even when that game ditched Easy AntiCheat.

Task Manager shows nothing suspicious. I tested the PC only with Steam and a few games a couple of times after a full reinstall yet the problem persists.

The PSU (Fractal Design Ion+ 2 Platinum (660W)) is original to build, being bought new & sealed in box 2 years ago.

This may or may not be related, but which type of USB are you plugging the receiver into, 2.0 or 3.0 ?
USB 2.0 is generally meant for peripherals.

Both 2.0 and 3.0 cause issues while wired and wireless with receiver.

Regarding:

Specific details?

What game(s)?

War Thunder. Last time I checked though it's no longer there (coincides with it not using Easy Anticheat anymore). No other details then that other than the fact that it still happens even when I'm just opening Microsoft Edge.

Try running "dism" and "sfc /scannow".

Done it again in case if it can fix it, doesn't seem to work. Both mouse and keyboard are still freezing randomly, and I started noticing it in different apps and games (Discord, Genshin, Valorant, the lot).

Another thing I can now confirm is that the motherboard's RGB controller are somewhat busted as well. Some of the LEDs seem to display different colours when set to a single colour (i.e. setting the color to all solid amber or red seems to set some to bright green).

Turn off all screen and power savers. Turn off all RGB effects.

Minimize apps etc. running in the background.

Objective being to simplify as much as possible and determine if the input problem stops.

Then, if so, you can slowly add things back to determine if and when the input problem returns.

The problem could be due to just the last thing added back but it could also be some combination of things.

Failing that the next step will be to use tools such as Task Manager, Resource Monitor, and Process Explorer to look for changes at the times of the input problems.

Their are a lot of users on here but have you tried something really simple unplugging the mouse and keyboard BEFORE you turn your pc on and then when your at the desktop plug them in. The reason i suggest this is because for some unknown reason my corsair straffe used to do a random light pattern as pc booted up and if it did i know i would not be able to type anything. Never did find out what caused it.

When your mouse and keyboard are acting up see if you can get them to work long enough to get into device manager , if you can has windows found them and do you have any yellow triangles next to their details.

Silly question ..... if you got rid of drivers software would you still be able to do what you want , i dont use driver on my corsair keyboard or logitec mouse i just use them as plug and play.

Done that in the past and I have done it again just in case if that last time was a fluke; it persists. I however did not clean reinstall Windows this time to make sure that it will mostly minimal with apps like last time, but with either only Genshin, only Discord, only Edge, or hell even just on the desktop without anything running in the background can still cause the freezing of either devices' inputs.

Task Manager doesn't seem to change at all, and as for Resource Monitor and Process Explorer I have basically no idea on what exactly to pinpoint.

That was actually my first go-to possible solution, and it doesn't seem to do a thing to fix it. Device manager have no yellow triangles to speak of, and I have reinstalled drivers of both devices multiple times; even those were the plug and play windows drivers, not any specific drivers from their respective websites (and to make sure of that I only installed the device specific drivers and apps that is mostly used for macros and RGB control on my laptop, which still have no issues with them both)

In Device Manager select the applicable keyboard or mouse device and then look at the presented tabs: General, Driver, Details, Events, and Power Management.

If you view the Events tab at the bottom is "View All Event" - clicking that button will lead into Event Viewer.

Look for any events/entries that occur just before or at the time inputs fail to register.

Resource Monitor and Process Explorer are dynamic and will change according to what the system is doing.

Try to watch for (or pinpoint) something that changes in any way when the inputs fail to register.

May be very quick or barely noticeable.

May take a bit of time and effort to get some sense of the information being provided and how to navigate within the tool.

Look closely at column headers: if you see an upward or downward point ">" that means that the column can be sorted in ascending or descending order.

Useful to discover processes that are most active and/or consuming system resources.

Something that could, in turn, be affecting the inputs.

Per @williamjeremiah - could well be something in the proprietary drivers/software.

"Taking over" in some way to update, backup, or simply phone home.

Actually, I just went to a different route for testing and decided to check if the PSU is the problem. I only have an electrical test pen (for now, just bought a multimeter online and waiting for it to arrive) and I noticed something weird. In Indonesia, we use a type F outlet & plug (Schuko) like Germany as shown in the picture below.
Glossary_type-F-German-electrical-plug-type-schuko.png

From what I read is that they are unpolarized or can be plugged in two ways. If the PSU is turned on, it can cause electric shocks no matter the orientation of the plug to the outlet. However, this is where I noticed something weird (to me at the very least); with the PSU switch turned off, one of the ways to plug the outlet seems to still be able to cause an electric shock. I was able to confirm this by using said electrical test pen on the shock points, including the ports of a monitor and the 3.5mm audio jack extension connected to the monitor if said monitor was plugged to the PC's GPU.

I still currently as me posting this have barely any idea if the PSU was the cause of the shock, or if my outlets were ungrounded. Other devices with grounding pins on their plugs seem to still light up the electrical test pen but definitely dimmer compared to when I touched my PC's multiple shock points using the electrical test pen.

EDIT: I did test using a multimeter. All voltage and resistance measurements seem to indicate that it probably is grounded at the outlet. What I'm still not sure to test is how to check IF the PSU was the one at fault, and if it actually caused the shock to the case and the random mouse freezing.

Currently I don't really have the time to test the Resource Monitor and Process Explorer, so I don't know if this is in any way a possible "symptom" to suggest that my PSU is the cause of my mouse and keyboard freezing problem.
