I recall it could be a tough situation, but I assisted a friend with a nearly identical problem recently. The incident happened when the PSU side of the power cables connected to his GPU became loose. It still provided enough contact occasionally, though it would suddenly stop working. Luckily, no damage occurred and repositioning the cable in the PSU resolved the issue. Beginning with the physical connections is always a solid first step. Inspect both ends of the power cables (CPU and GPU) and consider re-seating the video card. If you have another GPU nearby, try using it briefly to determine if the problem is GPU-specific. Although not everyone has a spare GPU, this can help. Another approach is checking the application and system logs in Windows after an event. Look for driver crashes or unexpected device removals. Determine whether the issue relates to the GPU or if there are other signs of trouble.
