Question Mouse and keyboard randomly don't register inputs - - so which part is at fault ?

[Stormzzy]

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 the issues on both 2.4Ghz wireless and wired.

The PC may not be able to properly charge the keyboard's battery. A PC USB port connection is being used to charge the keyboard - corrrect?

Are you able to try using an independently powered USB hub to recharge the keyboard?

The keyboard's battery may be beginning to faulter and fail. Perhaps a new rechargeble battery will help.

As for more wired freezes than wireless freezes the common factor is the use of USB ports.

How much more "freezing"? Quantify.

I can only speculate that maybe "wired" is more of a problem because the host PC is trying to process keyboard actions while recharging the battery at the same time.

In wireless mode (no physical connection to the PC) the focus would be on just keyboard actions via a dongle which would be in another USB port.

All involve "power" which orginates from the PSU. So the problems could be PSU related.

Key is to methodically work through some step-by-step testing to narrow down the potential culprits.

Change only one thing at a time while watching the logs and keeping notes.

And do find some time to look at Reliability History/Monitor and Event Viewer. Both tools are intended for troubleshooting use.

Error codes, warnings, and even informational events can provide clues. Or reveal some pattern that leads to the described freezes.

The keyboard's battery is fine as it has never been an issue for my laptop and any other laptop in my house to use it, so that can't be the case.

As for the freezing, with wireless it's random; if I have to quantify it, around 1-3 consecutive freezes every 5 minutes. With wired however, mostly every second.

And for the Reliability History and Event Viewer testing, funnily enough I have found one port that seems to be stable at the moment during testing and it decided to barely freeze at all with wired. One time that it really freeze, an error that both of them logged at the same time is a nvlddmkm 153 in Event Viewer and a LiveKernelEvent 141 in Reliability History. Have not seemed to have freeze more during testing, and the errors so far can't be replicated. Will continue to monitor as I'm currently forced to used said PC for After Effects work for my thesis since my laptop is not powerful enough.

EDIT: At the time of the edit, a second "cluster/consecutive" freeze have happened. It logged both of those errors again. And I forgot to mention that these only happen when the freezes happen consecutively, as there are some random freezes that did not produce these errors in the logs.

EDIT 2: I may have found a way to replicate the freezing problem. Scrubbing through After Effects footage with only vector components in it. Moving a part of the composition left and right fast enough cause the many parts of the composition to keep re-render and seems to freeze the mouse in the process. Although, from my knowledge those kind of freezing seems unrelated and is caused by the RAM instead.

I use "starter" because by reading the links (or similar links) you may become aware of other factors that could be involved.

Being able to duplicate the problem is very good. You can make other small changes (only one at a time of course) to determine if any given change makes the freezing better or worse.

Intermittent problems are difficult to troubleshoot. And it would very fortunate if someone reads your post and immediately recognizes the specific problem and can offer an immediate fix. No problem with that happening.

RAM: Where is the Pagefile located and how is the Pagefile configured? Should be auto - let Windows manage RAM for now, keeping in mind that perhaps more virtual memory made and kept available could help. TBD.

Also try disabling any unecessary tasks, utiltities, etc. that are launched at startup or later directly by you.

Purpose being to reduce the processing load on the system as much as possible. All components - including RAM.

Pagefile is on auto, and now I'm at least 75% sure it's the PSU. That After Effects moving around a part of a composition freeze only happens on wired. The nvlddmkm thing, I was aware that it was a supposed to be a crash but other than it happening at the same time as the freezing inputs nothing else really happens, and it only happens when a game was opened (despite the game running fine).

Any other test would have to be done at a later time as I'm currently quite busy and all of this discovery just happens while I'm using said PC for my thesis.

Keep your thesis documents constantly backed up.

At least 2 x and to locations away from the computer in question.

Verify that the backups are recoverable and readable.
