Question Losing all USB function for a few seconds

[blazeworks]

Hello.

Recently I've begun having a once a day hiccup with my PC. My sound, mouse, and keyboard will simply stop working for 3-5 seconds and then come back like nothing happened. Currently it has only happened while gaming and only once a day, but honestly I'd really like to figure out whats causing it even if its not that disruptive yet. There is no lead up to it happening, it just happens.

I have nothing overclocked besides XMP if that counts, my gpu is lightly underclocked and has been for a bit over 2 years. I ran a light [12 hours] memtest and my RAM came back fine from it, and between crystaldisk and samsung magician my drives all appear to be fine. I don't have spare components to throw in, so honestly I'm at a loss. When it first happened, my cat jumped onto my desk really hard and made it shift a bit so I thought it was just a weird effect from that but its happened daily since then without any prompt I can find. It has not frozen, shut itself down or needed to be force restarted since it started happening. I have an external dac/amp combo that was disconnecting on and off, so I swapped its ports and it solved the issue but I'm not sure if that'd be related. I also have been keeping HWinfo open to watch temps just to see and nothing is abnormally high or even above average.

My specs are -

Ryzen 5600x
Gigabyte b550 Aorus Elite
Crucial DDR4 3200mhz 32gb
Corsair 750 RMX
EVGA 3070ti
Samsung 970 Evo Plus
Samsung 850 Sata drive x2

Windows 10 Home



Any help or even just advice of something to check would be appreciated because I have no idea how to troubleshoot this at this point. If I missed any relevant info please let me know.

How old is that Cosair PSU?

Is the "once a day" time the same? 7:13 p.m.? Or perhaps some other pattern?

Also look in Reliability History/Monitor. The time line format may prove revealing and helpful.

Another place to look is Task Scheduler. Some other app causing the stoppage when triggered.

You mentioned using HWInfo to watch temps.

Another tool to use is Process Explorer (Microsoft, free).

If the time is consistent enough you can watch and determine what process changes occur when USB functionality is lost.

The PSU is about 2 years old, slightly younger than my GPU.

Once day currently seems to be just within 5 hours of booting the PC. It wouldn't be impossible to watch for something for a few hours, I'm just not sure of what to watch for. Reliability monitor just tells me it was a critical event and the time, which still isn't specific enough to say it always happens at X hour.

Task Scheduler doesn't seem to have anything going on when it happens, but I also haven't used this before so maybe I'm missing a part of its information.

Process Explorer looks promising as I'm not sure what else I can use to monitor changes, though I'm honestly a bit confused for what I should be looking for on it. I do see Hardware Interrupts listed which I assume would be what I'd wanna check?
