Is My Ethernet Connection Causing My PC to Lock up and BSOD?

For the past couple months, I have been through hell trying to figure out what is causing my PC to lock up. I brought it to my friends house and it runs absolutely perfect there with no issues ever. At my house though, It will randomly lock up and occasionally blue screen. Much of the time after blue screening, my graphics driver will be deleted then comes back. No idea why that happens pr if thats normal but I can assure you that my GPU is fine because these problems only happen at my house. The first 2 times I brought it to my friend's, I only brought a mouse and my PC itself. We used his monitor, keyboard and Ethernet cable. I figured that maybe it was my monitor or keyboard causing the issue but lock ups and blue screens still occurred when using different ones at my house. I then thought it might be my Ethernet connection. Are PCs known to have these problems from faulty connection? I did notice that on my modem/ wifi router that the ethernet light that my PC what hooked to would be red. I could not find answers on what that means

I could use alot of help because I am done with this and want my PC back and working.

I don't think it the internet connection. I would be interested in the BSOD error code. Have you looked at your event viewer? here is a weird idea... have you tried plugging the computer in a different socket at your home (on a different power line)

I've plugged it in all over my house but I have never tested it without being connected to my ethernet which is why
I'm thinking it is related to that. Like I said, at my friend's house with everything plugged in that I use at my house except for the ethernet, my PC runs perfectly with no issues. I bring it home and get lock up after lock up after lock up leading to blue screens after blue screens.

I've also did memory tests, checked cpu temps, updated drivers, checked my sockets for proper ampage, replaced my PSU, tested my PC with one GPU and then the other (I have crossfired r9 270X's) even testing with one RAM stick and then the other. I've ran it with all unnecessary USB devices disconnected as well as used a different monitor and keyboard. None of the tests showed anything wrong and the swapping of hardware led to the same problems.
