Random stuttering of sound and screen (for less than a second)

[mgoran]

This is a newly home built pc and after start-up (sometimes after a couple of minutes) it randomly stutters: short buzzing of sound paired with a short screen stutter. It also seems as if it takes a long time to shut down (the screen shuts down immediately but the fan and light keep running for a real long time, 10 minutes +)



Windows 10 Home 64bit

Processor: AMD Ryzen 7 3700X 8-Core Processor (16 CPUs) ~3.6Ghz

Graphics Card: NVIDIA GeForce RTX 2070

Motherboard: x570 AORUS PRO WIFIx507

Power supply: 850 B3 EVGA Bronze

Cooling: Corsair Hydro Series H115i Pro RGB

Memory: Corsair Vengeance LPX 32GB (2x16GB) DDR4 3000MHz C16 XMP 2,0 High Performance

Data: Crucial MX500 Internal SSD 3D NAND SATA 1TB and XPG SX8200 Pro internal solid state drive M.2 1000 GB PCI Express 3.0 3D TLC NVMe





I have tried:

turning off the audio enhancement

updating drivers











Thank you very much.

Ummm, there's no such thing as Ryzen 8. Please verify your CPU. I suspect you meant Ryzen 7 3700X, but maybe you meant Ryzen 7 3800X?

That definitely is not right. The computer, including fans and LEDs should go off within a couple seconds of the monitors.

Is the buzzing sound coming from the speakers or from inside the computer case?

Did you triple check to make sure you did not insert an extra standoff under the motherboard? Note that cases are designed to support 1000s of different motherboards. So, it is common for cases to have more motherboard mounting points than boards have mounting holes. A common mistake by the less experienced and distracted pros alike is to insert one or more extra standoff in the case under the motherboard. Any extra standoff creates the potential for an electrical “short” in one or more circuits. The result ranges from "nothing" happens (everything works perfectly) to odd "intermittent” problems to "nothing" happens (as in nothing works at all ). So, you might pull the motherboard to verify there are no foreign objects (like a missing screw) and that you only inserted a standoff where there is a corresponding motherboard mounting hole. Fortunately, in most (not all, but most) cases, removing the extra standoff(s) or foreign object restores proper operation with no permanent damage.

Note this is also a good time to assemble the computer outside the case on a large bread/cutting board or plain cardboard (some non-conducting, unfinished, unpainted surface) to see if the problem persists. Do NOT use the motherboard box as the inks used to print the labeling and marketing information on those boxes often contain metals and other conducting materials.

And since everything depends on good, clean, stable power, I would at this time try a different power supply too. Swapping power supplies also provides an opportunity to ensure all power connections are correct and securely fastened. While EVGA is my preferred brand, until Man can create perfection 100% of the time, even the best makers occasionally produce a product that fails prematurely.

Also, poor grounds and/or interference can cause buzzing sounds. Make sure all your data and power connections are tight and secure. If they are, ensure your wall outlet is properly wired. Every home and every computer user should have access to a AC Outlet Tester to ensure the wall outlet is properly wired and grounded to Earth ground. I recommend one with a GFCI (ground fault circuit interrupt) indicator as it can be used to test bathroom and kitchen outlets (outlets near water) too. These testers can be found for your type and voltage outlet, foreign or domestic, (like this one for the UK) at most home improvement stores, or even the electrical department at Wal-Mart. Use it to test all the outlets in the home and if a fault is shown, have it fixed by a qualified electrician.

If all good, I would try 1 stick of RAM at a time and see what happens.

sounds like bios issue

Thank you for the quick reply.

The buzzing is coming from the headphones/speakers.

I will try out the aforementioned solutions.

Keep us posted.

 

[xtreemchaos]

id try a bios and driver update and maybe a chipset too if theres a newer one.

 

[mgoran]

Keep us posted.

Haven't had time to do it yet.
Before reconstructing the hardware (I had someone do it and he isn't available right now), should I maybe try a bios and driver update first? And how should I go on about that (clean install the drivers manually?). My other significant tried the pc out and told me that in the three times she tried, it worked smoothly twice (and also shut off as it should have) but one time it started stuttering quite soon. She played video games during these two times, the other time it started stuttering she put on a song on spotify.

Thanks for the quick replies.

That's up to you but I generally am not a fan of updating the BIOS unless the update addresses a problem I am having. If the motherboard has been in production for awhile, the bugs are typically already worked out and most updates from that point on typically just add support for new components, like new CPUs or new RAM that came out since the board left the factory.

The buzzing can really only come from two places : graphics card or PSU. That is if it's external, if it's internal from speakers and such it's probably a grounding issue.

It also seems as if it takes a long time to shut down (the screen shuts down immediately but the fan and light keep running for a real long time, 10 minutes +)

Something is leaking current into your PC, that's really bad. I've know someone had a similar issue on here it had to do with some kind of DP cable, can't remember the specifics. His monitor was driving current back into the PC making some of the fans spin even when the system was off. Really bizarre stuff.

Don't know if it was clear but I'll edit it. The buzzing is internal, it's like when there would be a scratch on a cd or an error in the sound, the sound stutters. It comes from the speakers but it is paired with a slight screen freeze.

The leakage would seem odd, it had the same issues on two separate occasions, different cables and environments.
The system isn't truly off, all the rest keeps on running.

Alright, might end up reassembling it, going to try a quick driver update (not BIOS). Just odd that the problem happens randomly.
I have noticed that the small fan of my motherboard is not spinning, when it doesn't spin the sound and screen stuttering persist, after a while it started spinning and the stuttering disappeared. So I think that is the culprit.

I forgot to mention it is in a mini itx case, which is compact and needs a lot of cooling. The fan wouldn't start if the temp didn't go above a certain degree, so now I am running the fan on the motherboard at full speed all the time instead of the standard setting and there is no more stuttering. I think might have solved the problem. EDIT: seems it didn't help after all.
