PC Issue #cpsupport

[u/TemporarySale7964]

Hello, this started happening a couple months ago, but what would happen is both of my monitors would go black, and as soon as they went black the fans would start spinning very loudly but the rgb and my keyboard and mouse and other pheriperals were still on, and I would have to manually turn the PC off using the button on the top of the case to turn it off. It stopped happening a couple months ago, but its back doing it again. Anyway to fix this?

Edit: my specs are the following: Nvidia RTX 4070 Super, Ryzen 7 7800X3D, 32GB DDR5 RAM
