Hello

A friend of mine has been using the same PC for the last say 2 years. Suddnley his internet begind knocking on and off, for seconds at a time. His USB periferals will stop working, before reconecting, and the Display port from the GPU will randomly disconnect and then reconnect.

There is a lag aswell, when typing sometimes the PC will lag behind the keys, and then catch up.

When the PC not connected to the Router, and you use devices with WIFI, the internet works fine.

He has updated the BIOS, and till the issue persists. No idea whats causing it. Any ideas?
