Computer freezes with black screen

[Shishir]

Hello,

lately my computer is freezing up with screen completely black  while in the middle of a zoom meeting. I have tried all kinds of things. I have done a clean USB install of my windows 11 23H2. No idea what is going on. The hardware checks out with all the tools built into my HP pavillion lptop. ANt help would be greatly appreciated.

Thanks much
