@crossshot Perhaps. Definitely not ruling it out, it actually sounds rather possible. I just wonder how I could go about debugging/fixing it (besides sending over to PCS again - I imagine they'd have much more success fixing it if it was easier to reproduce).

@solidus1983 1.07.08. I believe that PCS folks upgraded it to latest PCS BIOS when installing my new motherboard. EventLog doesn't say anything of value from what I can see. It's hard to navigate it, but these disconnections are frequent and really brief, and I see nothing that would match this pattern. Note that the audio crackling and USB disconnections are happening at the same time - so looks like they're most likely related. We had suspicions that it was power distribution issue - that's why mobo got replaced, but yeah, the problem still persists.

@solidus1983 I can try that tomorrow. I did drivers reinstalling as one of the first things before RMA - PCS folks also got me to use DDU. I also did a full OS reinstall after first RMA. But I can still try, it won't hurt. But would that be causing USB peripherals disconnecting?

I've had Clevo X170KM-G with i9 11900K and RTX 3080 for a year now, and past few months been experiencing some annoying issue. Seemingly depending on temps, it starts misbehaving - audio gets a really crackling noise, then USB peripherals begin to briefly disconnect just to reconnect after anything between 0.2 to 3 seconds. This mainly happens when gaming when fans are full speed but heat builds anyway, and when fans are set to quiet in CCC, even when just Spotifying/running UserBenchmark. It happens with or without any peripheral devices used, but external speaker makes it more noticeable. The issue seems to appear inconsistently making it difficult to reproduce, but it does happen frequently enough to be really annoying. I sent the laptop for RMA twice, and the folks at PCSpecialist tried their best to reproduce and communicate, but it's been difficult cause of the nature of the problem. Last time they replaced motherboard and GPU entirely, and it seems to have improved the issue somewhat (been able to game for a few hours without a problem), but it didn't solve it (experiencing it as we speak with Cartel Tycoon running in the background). I also tried to determine if it could be faulty RAM, but I believe this can be eliminated - I tried with only one stick being plugged in at once - reproduced with both sticks this way. So unless they both have issues, it's not RAM. With many components replaced, I feel like there's little to go with - CPU being most likely. There's also 3 SSDs, but I honestly doubt it's them - and in fact I even determined that it happens with one of them removed, didn't check other 2. I plan on messaging PCSpecialist yet again this monday. My warranty runs out this month, so I hope to get it sorted ASAP. Did anyone ever come across this issue? Over past 2-3 month, a bunch of IT people were brainstorming this (myself, my friends, support and engineering employees over at PCSpecialist) and we all are seriously confused at this point.
