Issue with LAN cable connection leads to system crash.
Issue with LAN cable connection leads to system crash.
Hello everyone.
I’m facing a specific issue: when I connect my LAN cable to my computer, it crashes.
The Event Viewer shows the error details here:
https://paste.gg/p/anonymous/188ec3f3b01...375ecce7fb
(the XML version of the error).
When does this happen?
- Whenever I plug in my Ethernet cable while the PC is running
- If I connect it before the PC starts up, the system doesn’t even begin
What I’ve tried:
- Installed all updates and drivers
- Reinstalled the OS
- Performed a BIOS reset
- Updated LAN drivers
My hardware and software:
- Gigabyte B560 DS3H v2
- Intel i5 11400f
- 16 GB RAM
- RTX 4070 super
- Windows 11
I’m hoping someone can assist me. Thank you for your time.
Unfortunately the event details you posted simply say that the PC rebooted or shutdown unexpectedly.
The symptoms you described, and the steps you've taken to resolve it, sounds like it's a hardware fault.
As a workaround you may want to consider a USB Ethernet adapter. There's no 100% guarantee that it'll work but you may be able to return it for a refund if it doesn't.
It's quite unusual. Even if it doesn't seem likely, what occurs when you insert a LAN cable without connecting anything else? Does the type of connection matter? If you simply power on the BIOS and then connect the cable, does the system crash or only when Windows is active? I imagine the issue might be related to the Ethernet chip being disabled, causing the port to activate only when an Ethernet cable is present. It could be a power-related problem making the chip consume excessive power. The best solution seems to be using a PCIe Ethernet card with an extra slot or a USB adapter, preferably with USB3 ports for high-speed performance.
It is rare to understand why certain electronics malfunction. A component may simply fail due to a manufacturing flaw, becoming defective only after prolonged use. There is nothing on the motherboard that can be replaced. The most affordable option is to try a new Ethernet card, but if the motherboard has power regulation issues, the replacement might also prevent the system from booting. You are essentially left with replacing parts one by one to identify the problem. I recommend starting with the Ethernet card since it’s inexpensive. After that, consider checking the power supply or the motherboard itself. As you progress down this process, you need to decide whether investing in an older platform is worthwhile or if it’s better to keep your graphics card and upgrade the rest.
Verify that the back panel (I/O shield) is properly installed and ensure no spring sheets are making contact with the inner contacts of USB or LAN ports. Consider taking photos of your build from all angles, both inside and outside, and upload them to a platform like imgur.com.
This is an excellent suggestion. A picture of the back panel (where all the cables attach), might be enlightening.
Anything protruding into a port (like those little grounding fingers) can cause this. A misaligned I/O plate may also cause a short condition.
