Need Help with peripheral disconnects during landings

[Shrive81]

Hey Gents, 

 

So been chasing an issue and I have been working on my case 3 landings and as i start my decent into the ship almost every single time i have been getting all my winwing peripherals disconnecting and instantly reconnecting along with Reverb G2 screen going grey for a secoond or two then all coming back. I have all my peripherals on a powered USB hub and I have already replaced it with a new one thinking that could be the issue the VR is plugged straight into the computer. I dont have reallyt any issues when flying around but does seem to happen during heavy load on the system like computing lots of stuff in DCS if that makes any sense it happened in a dog fight last week.

 

My computer is new:

intel i9 13900k

rtx 4090

64gb corsair ddr5 ram

2TB hard drive

legion mother board and case

 

Not sure what exactly to do its causing issues with possiblyh joing groups online and squads

 

Any help would be great..

 

All temps are good as well on the GPU

TBH it sounds as if there could be a power problem - but it would seem not to be a problem with the USB devices/the hub (as you've indicated it's a powered hub and been replaced).

The part about it happening when there's more of a load also more or less suggests power problem (to me).  Even though you indicate good GPU temps, that isn't necessarily the temp that might cause problems (though it won't help if it's hot, and could be part of the issue).  Have you looked at CPU temps?

Inside the PC (with a very few notable exceptions), the USB ports are contained within the CPU itself and the chipset (which of these it's in depends on which port).  It sounds like either the CPU or chipset dumps the USB ports eventually during your gaming, possibly as a result of getting too hot.  Could also be a power fluctuation as the PSU itself heats up.

Speaking of which, how's the PC arranged?  It's not sitting on something like a carpeted floor, is it?   The PSU only really has one intake for cool air, and it's underneath the computer.  If the computer sits on carpet, the weight pushes the case down into the carpet and can block the PSU intake altogether.  (As an aside, they didn't mount the PSU with the fan intake facing inside the chassis...did they?)

Try running with the case open.  I'd also consider directing a fan at the open chassis during some test flights - this is all temporary, as a test, to see if better ventilation will help.

Also: By "Legion mother board and case" I'm assuming you mean a Lenovo Legion - is this correct?  Be aware, Lenovo doesn't make motherboards (or really any of the other guts).  They rebrand stuff from OEMs, sometimes custom designs by Lenovo, sometimes not.  This would apply both to the motherboard and the power supply.

If you can provide more details on the internals: Specifically the motherboard and power supply, this may help nail down where the issue is - although be forewarned, sometimes they intentionally obscure (or even forbid) any type of labeling by component providers.  Seemingly simple stuff like requiring the PSU label to be places such that it's not visible once installed in the machine.

Unfortunately, these 'pre-built' companies tend to use cheap parts in many instances.  Cheap motherboard designs and cheap power supply designs are not uncommon.  I hope I'm not stepping on any toes here, but this has been my overwhelming experience across more than 4 decades building PCs.

What about warranty?  You mention the machine is new - have you been in contact with the company who has the support obligation?  Often, people buy machines from Dell, HP, iBuyPower etc, because of the name.  The idea is with a 'big name' company, it must be a good system.  But the name is really only as good as whether they support the hardware they sold.

By the way: You have a 4090 GPU.  They require a lot of power.  Depending on a number of particulars, it's entirely possible your PSU isn't keeping up with the 4090. Can you provide the exact manufacturer and model number of your 4090, please?

I would try this: go to power plan and change advanced power settings and then disable USB suspend. See if that helps.

When you say powered hub, is it USB 3.0 and what's the power rating?? Not all "powered" hubs are created equal
