Processor Internet problem since new Internet provider

Hello,

since I changed my Internet provider (Unitymedia to Vodafone) I got many Internet problems.

The problem is:

When I'm downloading something, My whole pc is lagging (especially sound).

When I look in the task manager I can see that the 1st Core is at 100%.

By the way the problem is not my new Internet provider, when I switch my Lan-Cable to an other PC, all works fine.

The Lan Cable is not the problem as well (as mentioned above).

I also updated all drives (Using AMDs Update Software).

But it still doesn't work and I don't know why.

Best greetings

Robert

Some anti-virus software can do that.  I know BitDefender did that after an update, and have no idea if they've since fixed it, since I had to uninstall it.

If you don't have any third-party AV installed, then it would be something else.  You need to check what process is actually using the CPU.

I deinstalled my anti-virus software.

Also maybe check your DPC latency.

Here's a thread that shows you some basic tweaks that can help you.

Then you can download Latencymon to see which driver is giving you problems. https://www.sweetwater.com/sweetcare/articles/solving-dpc-latency-issues/

Hallo alle zusammen, ich habe das Problem gelöst. Grund für diese Ruckler war ein Programm Namens cFosSpeed welches auf meinem PC installiert war. Ich selber erinnere mich nicht mehr daran das ich dieses Programm installiert habe, wahrscheinlich ist es über einen Chip Installer mit rein gekommen keine Ahnung. Jedenfalls ist das Programm jetzt weg. Danke sehr für eure Hilfe. Liebe Grüße Robert
