I had this problem on my laptop earlier and it was corrected when I noticed the ram hadn't fully clipped in. Not this time on my deskptop with all still pluged in when turned off, I just swapped the m.2 ssd and had just ran one new preinstalled with win 11, but now I get no signal, all power, but no lights on the usb wifi unit. I think It may be related to running the same Win key on two systems both which were upgraded to win 11 home, because the second one on the laptop couldn't download anything, Edge wasn't installed and wasn't able to be downloaded. I back installed Win 10 on the new Gen 4 980 Pro and poped it on my desktop to find it partly dead, well lit and fans running, but no glory.
