    100% cpu usage from system interrupts only when I plug my ethernet cable

    Yesterday I moved out of my old home and went to install my setup and when I turned on my laptop I noticed it was freezing for long periods of time, when I managed to open task manager I found out that system interrupts uses between 20-100% of my cpu. When I was trying different things to fix it I unplugged the ethernet cord from the laptop and the system interrupts never went over 1%. I tried a lot of different methods to fix this:
    -I updated the windows drivers
    -I used a malware scan
    -I disabled wake on magic packet and wake on pattern match (witch fixed it for 30 minutes)
    -I disabled high precision events
    And still no fix, I taught that it’s from the wall socket in witch I connected the cable but other people that are connected to the same network don’t have this problem. So please somebody help me fix this.

        Download Process explorer.
        Process Explorer - Windows Sysinternals
        Drag procexp64.exe onto your desktop.
        Right click and run as admin.
        Screen shot the item that is chewing the CPU
        Then right click the item select properties.
        Then click on services. Screen shot that for me.
        Then click on threads tab and screen shot that for me
