Windows 10: My Network Crashes Suddenly

Since 4 days my network is suddenly crashing. It crashes everyday without any warning or something and there is no pattern so it sometimes crashes after 1 hour sometimes after 1 min and it happens like 5 or more times a day. Im using a Network amplifier, which is connected to my whole pc with an extension cable. So if i pull out the amplifier my whole pc turns off and after putting it in again my network works as usual until it crashes again. I also tried another amplifier and another LAN cable nothing works. The amplifier also works on my brothers pc normally.[moved from de-de]

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

Network suddenly changed?

For the longest time my ethernet had been recognized as Network 2.

Today, suddenly I was prompted to select whether other computers in the network should be able to see my PC, as usual when connecting to a new network. I then noticed my connection had suddenly been changed to use Network 5, with Network 2 no longer being
in the list.

Why would this suddenly change? It's not really a problem, I am just curious as to why this suddenly happened.

I haven't changed anything myself so this seems rather odd.

 

W10 Settings crashes when going into Network & Internet

Same issue for me, when entering Network Settings, panel crashes. Device Manager says network devices are working but I have no network. Tried all the steps suggested in prior feed.
