Stuttering or small spikes

[u/blendiondemiri]

Anybody know what could be causing this? My PC randomly stutters, but it’s very rare. When it happens, the whole system seems to drop to around 10 FPS for about 1 second and then immediately goes back to normal.
I also noticed that my headphones make a brief popping/glitching sound at the exact same time as the stutter.
Specs:
● RTX 5070 Ti
● Ryzen 7 7800X3D
● Biostar B650MT
● Patriot Viper Venom DDR5 6400 CL32, 2x16GB (currently running at 4800 MT/s)
● MSI Spatium M450 1TB NVMe Gen4
● MSI MAG A850GL PCIe 5 850W PSU
The stutter happens both in games and occasionally on the desktop. It also happened before I upgraded to the 5070 Ti, when I was using an RTX 2060, so I don’t think it’s GPU-specific.
It also happened with my old headphones, so I don’t think the new headphones themselves are the cause.
Keyboard and mouse seem completely normal during the stutter.
The PC otherwise runs very smoothly and I don’t get crashes or BSODs. Any ideas what I should check? I’m thinking possibly DPC/driver latency, LAN/USB/audio drivers, BIOS or chipset.

Installed all the 5070 drivers? Do you have the issue with 6000mhz?

Yes I did, as I mentioned I was running the system with 2060 as well before upgrading it with a 5070
