CPU model: 12th Gen Intel® Core™ i5-12600K. GPU: GA106 [GeForce RTX 3060 Lite Hash Rate] from NVIDIA. Motherboard: Z690 UD DDR4 by Gigabyte Technology Co., Ltd. RAM: 2x16GiB DIMM DDR4, synchronized at 2133 MHz CMK32GX4M2D3600C18 via Corsair WLAN Stick: FRITZ!WLAN AC 860 by AVM. Screens: 2TB HDD 5WD Blue SN570 500GB SSD (OS installed on SSD). OS: POP-OS 22.04 / Windows 10* 700W Power Supply* (*details available elsewhere*).

Here’s what occurred. (Using Windows 10 with a 650W PSU) Initially, my internet would drop unpredictably—sometimes the LAN adapter would disconnect, other times I’d see “No Internet, Secured.” Occasionally, restarting fixed it, but shutdowns were problematic; the PC would hang for unusually long periods, sometimes up to an hour.

Eventually, about six months ago, my PC stopped powering on entirely. A repair shop diagnosed a faulty PSU and recommended a 700W unit. Replacing it resolved the issue, but internet and shutdown issues remained. I explored registry tweaks to see if they helped, but found little success.

A website would load briefly when connected, then my connection would fail immediately—either by clicking or waiting too long. The LAN adapter would work fine with an Ethernet cable, but not with a different PC sharing WiFi. Windows’ troubleshooter flagged an invalid IP config and attempted fixes that didn’t help. I noticed occasional IP negotiation failures.

Yesterday, frustration peaked when the OS changed to POP-OS and internet worked again, though I still saw pop-ups warning “network connection failed.” I could browse for school but wanted to play games. I set up a VM with VirtualBox, but it only supported OpenGL 1.1—insufficient for my games. QEMU/KVM didn’t work either.

When booting POP-OS, the screen stayed black after pressing F12 into BIOS; it would shut down on its own during a prolonged session. I tried reinstalling Windows 10 to see if a clean install would help, but it failed—my second screen didn’t appear and my first had poor resolution.

Somehow, when I connected via phone (mobile data off) in the same WiFi, internet worked. Changing contracts and getting a new router didn’t resolve the problem. Another POP-OS installation had 4 boot devices: UEFI, Windows Boot Manager, UEFI OS, and Pop!_OS. The boot process was confusing but functional.

My available RAM was 447.5 GB / 481.6 GB free. Firefox works for school tasks, but I still need guidance on the hardware issue. Any advice would be greatly appreciated. Thanks for your time.
