RTX 4070 Black Screen (of death) issues

MY PC with an RTX 4070 has been black screen for the past month or two pretty much daily and I've been unable to get it back up until I do a hard reset by holding down the power button. I've seen the headlines about issues with drivers, so decided to rollback driver to before 50 series launch. I think the latest one was in Dec 2024. This morning it black screened again. I also have the new Nvidia App installed, could that be the issue? Has anyone found a rollback driver that worked for them? I tried updating to the latest one since it said it fixed the issue for RTX 50 series, but a few hours after when went to unlock my PC, it black screened again. I always restart my PC after doing a driver install, and have done the clean install each time.

I have Best Buys Total membership and I'm 1 month out from being able to go through that to fix it (or change it out, not sure which they will do). Should I just take it to them and see what they can do for me?
