Question disconnections for seconds or longer and display port problem

Hi,

My ethernet disconnects randomly for seconds or for 10minutes where it stops showing like anything is connected to my pc(ethernet cable). I am so frustrated, desperated and need help from someone with high tech knowledge. These are not only in specific software, I changed motherboard they are still there (dcs), then changed cpu, rams still.

So friend recommended me to reinstall windows without nvme m2 drive and see if it was the issue. Now it's all wasn't fixed I'm so done spend thousands of dollars, always something happens to my pc only, when I don't download some sketchy softwares or anything. So my ethernet cable was cat 8 changed to cat 6 monoprice, because everyone recommended me to. My roommate doesn't have any dcs.

I tried almost everything, basic stuff, installed new drivers to lan, restored them to older to see if it maybe will be good. Still no fix, I don't know what to do for now. Can graphics card be the issue? Because today also display ports ( both) stopped working. Hdmi worked, then connected again after like 10 hours and worked but on less hz than I had on pc whole life. If i choosed higher refresh rate than 240 it would just be black screen with display port. But the worst is it barely works, because monitor ( model aw2521h) started to turn off randomly my monitor saying no signal and coming back, one time it was this long I needed to reconnect the cable strongly for it to work. That's last component and my 2 other drives that weren't replaced.

What should I do at this moment? order new graphics card? i will go bankrupcy in a while, always something happens. What should I do at this point? Please help asap, this thing is going on for 2 months from now. Is display port problem related with disconnects? Also it's weird but after chipset installation was ok and next day it just stopped working. Tried both ports on monitor and pc (4 together).

None worked, these are actually two issues and I need to fix them, it really bothers me too much.

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Troubleshooting doesn't mean you throw money at the problem, instead you borrow parts from your friend or neighbor and test them out. To add, I've read that you replaced parts, might want to mention what parts were swapped as in a before and after of your specs.

To me, it looks like a wall outlet/power strip issue.

Moved thread from Networking section to Systems section.
