Question Strange problem, when using full internet speed it's freezes windows.


Jun 21, 2016
I'm having some throuble trying to figure out what is going on...
Maybe someone here have some answer or can help me with some troubleshooting...

I've upgraded my local networking of 50mbps to 300mbps and the chaos begins!
When I do any internet speed test, my computer starts to do some random 1 sec freezes until the download test stops (no freezes with upload test).
It's impossible to do anything when I'm downloading with full speed on steam, torrent, or anything.
I've notice that when I'm downloading, my CPU core 0 and 2 go to 100% for some seconds, but normaly the CPU total usage maintain at 10-20%.

Has someone experienced any issue like this?

I forget to mention, my anti-virus is turned off and rarely sometimes this weird issues is gone... It's really weird!

My config:
CPU: Intel i9-9900K @ 4,70GHz
RAM: 2x 8GB HyperX Fury (2933MHz)
GPU: MSI GeForce 1070 Ti (v:471.41)
MOBO: MSI x390 Gaming Pro Carbon (v:7B17v1B)
WINDOWS: 10 PRO (v:20H2)
Main HD: NVME Samsung Evo 970 500GB
