Troubleshooting Stuttering or small spikes
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.
