I have the same issue, but i have no idea at 100% whats causing it.

Does anyone else have the same issue?
I don’t know how i can add any screen shot from the scan here other than maybe using my phone to take a picture of it…

As for what’s causing it, at first i thought i might be the updates from Norton 360 ver.24.x.x itself but seeing how old your post is and that this issue started for me only very recently (about a week ago) i can think of only maybe 1 thing that changed deeply on my PC that MAYBE could be causing it. It woukd be ever since i got a update of my BIOS to it’s newest version done.

From i quick glance i could see something about memory and SPD write protection that could be enabled in it now and comes turned ON by default after the update of the BIOS… i would need to check it at home on i get back (i wrote while on break at work) :sweat_smile:. But as i said im not sure if it’s that…
