The title clearly indicates the problem. Online reports suggest that a sudden loss of display and spinning fans usually point to overheating. I understand it isn’t overheating since the Task Manager shows my GPU temperature averaging around 35°C with only light load reaching 55-60°C during games, and the peak temperature on one core is about 55°C according to Core Temp. This issue has been ongoing for some time, leading me to suspect PSU or fan-related problems. I purchased a new PSU, upgraded the case for better airflow, and added two more fans (making four total), hoping it would stop the overheating, but it hasn’t resolved the matter. My main concern now is that the RAM might be defective, as my friend gave me the modules during an upgrade thinking they were faulty—though tests confirm they’re working fine. Here are the specifications:

Mobo: Gigabyte B660 GAMING X AX DDR4 LGA1700
CPU: i5-12600KF with Noctua NH-U12S cooler
GPU: Gigabyte Windforce OC RTX 4070 Ti
RAM: Corsair Vengeance 8GB DDR4 2400 x2
PSU: Corsair RM750x 750W Gold
OS: Windows 11

Often a sudden black screen, particularly when graphics load and fans spin at maximum speed, may indicate a power delivery issue (GPU/PSU or cabling). If you've already tested multiple power supplies and checked the card on another machine, it might be the most effective next action. Improving memory speed could significantly boost performance, though I suspect the problem lies elsewhere.

I considered it might be a power delivery issue too, but this also occurred 2 seconds after I powered on. It's possible that daisy chaining the PCIE cable to the GPU instead of using two separate cables could be the cause.
I tried using the card on my friend's PC and it worked, though it was in there for about 5 minutes.
