After that post, I planned to bring it to repair. Because the MSI repair location is under lockdown, so I have to wait.

Yesterday, I was thinking to give it a shot again. Reinstalled my 3070ti, and it worked! And I played game and no problem, shut down computer. Then today afternoon, the problem occur again, MSI motherboard EZdebug light is on the GPU.

Why the GPU works again after a week of not using it? Is it something wrong with my build? Not enough power?
