All my peripherals keep disconnecting!

[Quixotic]

Hey LTT, coming at you with an irritating problem. I have this issue where every so often, all of my USB devices will just disconnect for a few seconds and then reconnect. At first I thought it was my minifridge messing with the power or something, but even after unplugging it the problem keeps happening. My keyboard goes out, my mouse goes out, the USB mic goes out, and even the USB header for my H100i V2 says it's disconnected. After maybe 5 seconds, everything comes back.

 

The one solution I saw for this was to change the USB power settings in my power plan, but I already have the selective suspend setting Disabled, so it's not that. At this point I'm thinking it's either the PSU (at this point an 8-year-old Corsair 750TX), or my motherboard, a Gigabyte X99P SLI. I don't think it's the PSU though, because I can run my GPU at 100% all night and it doesn't fluctuate in power or anything.

 

The weirdest part, though, is that this wasn't happening for the past 3 months when I was staying at a friend's place. Maybe because I had less USB devices plugged in?

I'm having the same issue, except my keyboard keeps disconnecting and nothing else. My AUX ports just completely don't work, but its probably the board that's causing the issue.

 

I plugged in my keyboard into someone else computer overnight, because when it dies and powers on it gets set to the default rainbow color so I can tell it died. So far it doesn't seem to have died.

 

It looks like it could be the PSU, but that would be really weird because quite literally all my other peripherals work flawlessly.

Alright, I did a little testing, but I'm not closer to an answer.

 

While playing Overwatch, I disconnected every USB device that wasn't my mouse, keyboard, or microphone. Problem still persisted. I then turned off my two side monitors (I have a triple setup), and the problem persisted. Unplugged the monitors from the wall, and from the PC, and the problem didn't fully go away, but it happened much less frequently.

 

Maybe the GPU is drawing too much power from the motherboard and it's hitting a threshold on my PSU that's making the devices drop out temporarily?

Another update. Bought a brand new PSU, the Corsair CS650M (Which still has ketchup and mustard cables??), and... the problem still occurs. One thing I forgot to note is that when the devices disconnect, two of my three monitors go to black, then come back. But this only happens if I'm playing a game in full-screen mode.

 

This problem gets weirder by the second. Luckily, I still have a Microcenter warranty for my motherboard, so maybe I can return that tomorrow and either get a replacement or a different one altogether. It's either that or reinstall my OS, neither of which I'm too keen on.

What do the windows application and system logs say? Any events in them when the fault occurs?

 

those errors are hard to track. but seriously a mini fridge onto the onboard usb ?! 

 

It could very well be that with all the peripherials connected without using a powered usb switch killed some parts of the mainboard. 

 

Think about it, the USB ports are for pperipherials like drives, sticks, mouse, keyboard, some ports even special for charging phones etc. 

 

Else but the mainboard comes to mind:

 

Driver issue, whacky wallplug delivering unstable voltage to the psu.

LOL, a USB minifridge would be tight, but it's just a regular one plugged into a different outlet in my room. My PC equipment is plugged into the wall behind my desk, and the fridge is on the wall to my right.

 

As far as windows events, I never got a chance to check. I'm currently resetting Windows, so if it continues after that I'll see if there are any event logs.

Ah I see... 

 

I said that about the fridge because there are actually some peripherials like a minifridge to fit a soda can that is USB powered, or coffee cup warmer... =)

 

Only thinig missing would be an USB powered mini microwave.

Alright, final update. The problem seems to be fixed after reinstalling Windows 10, so I guess it was some deep driver issue that I wasn't able to fix just by reinstalling the drivers. Didn't need that new PSU after all.
