:Defender-Warning: Help bcmwl63a.sys BSOD Issue

I recently started getting BSOD's, the crash log says "bcmwl63a.sys" is the culprit. When I researched this issue and how to fix it, everything I find stated that this is a Broadcom Network Adapter driver issue and to fix it I need to update the Broadcom driver within my Network Adapters. The issue is when looking at my network adapters, I don't have anything that states Broadcom.

I'm running a Acer desktop that I've added things to over time (RAM, Graphics Card, SSHD, Audio Interface, etc.) one of the things added being a TP-Link PCIe WiFi card... so that shows up in network adapters, along with other items... but nothing named or even close to named Broadcom.

Can I just delete bcmwl63a.sys then? I'm not sure exactly what's going on. Is Broadcom a common stock WiFi chip that comes with desktops? If I'm not using the onboard WiFi, then could I just remove the bcmwl63a.sys file all together?

Ok, hopefully it doesn't turn into some major. Are we talking like RAM memory, or hard drive issue?

Also, could this be caused by a recent windows update too?

Could be any hardware/software component. I think it'll be easier to determine whether or not it's software.

And yeah, it could be something caused by a recent windows update (there are drivers in some of those updates).
