The computer screen shuts down during gaming?
I just noticed you mentioned it was done on the previous card and PSU too. It seems there might be a shared item in there that could be re-added or involved in the issue when setting up from the old configuration. Figuring out which variable is responsible might be trickier than it looks. For fun, try turning off your AV software and then either play a game again or run 3dmark to see if the problem persists.
I performed a GPU stress test; the display stopped after about 20 seconds, and it happened again when the case was open. To be certain whether the issue is with the PSU or overheating, I plan to use the GTX 1060 with the same PSU and board, run a stress test, and observe the outcome.
The other GPU performed well and there was no black screen. The RTX 3070 temperatures are rising to 88-89°C, which is high; how can I lower them? Also, it looks like the issue might be related to the provided link since I have the same TUF gaming card.
You might consider reducing the volume on the card as recommended in the link, but proceed with caution.
Sounds like the cards are overheating. The 'GPU' is the actual processor itself, and for many cards that's the only registered temp. However, that's not including the VRAM and VRM's, which are not part of the 'GPU' as such, but do sit under the heatsink and generally a different area of the fan coverage.
If there's little actual airflow over the gpu area, it'll sit in its own heat, getting hotter by the second with no relief. It's entirely possible for either the VRM's or the VRAM to exceed 99°C+ and the 'GPU' never see north of 85°C.
Black screens or loss of signal but retaining audio is almost always a VRAM issue, but can also be a driver conflict.
Solved. The issue was due to overheating (85-89°C). I replaced the thermal paste, but it dried out completely and didn't fix things. It turned out the paste quality was poor. After that, a technician applied a better paste which reduced temperatures to the 70s under full load. I also added three more fans, and the temperature dropped into the 60s. The problem is now resolved. Thanks everyone for your help.
