Solved BSOD system thread exception L1C63x64.sys win8.1

[thebigticket]

I uninstalled the wired network card and then used only the wireless network card to connect to the internet
I was able to use the internet with no BSOD

So i guess the problem is a faulty wired network card

should i replace the wired network card with the same card as the original hp?

I would purchase a card that satisfies your needs.
Preferably one that advertises that it has Gigabit Ethernet.
But these are fairly cheap (about $10 US online).
Just make sure that they are Win8.1 compatible.

PS - make sure that it fits the slots that you have available on your motherboard (look up the specs at the HP support website).
Good luck!
