Looking for recommendations on how to diagnose this weird issue I had for the second time today while playing Baldur's Gate. Previous time it happened was playing wow.

Anyway, what happens is my screens all go black but the game is still running, just no video output. I can still hear discord, the game running, music going etc. Just no video out.

My GPU seems to run hot for my taste (80C max) during intensive times playing games but from what I read that is a totally safe temp for a 3080. Generally around 50-65 though during normal play

For reference, I had this card for a while but just rebuilt most of my PC with a new processor, motherboard, 1000W PSU, new ram and case that I put extra fans in. This happened once in my old build and now a second in my new one.

Is this an issue with the card, the power going to it not being sufficient or something else... I am well under the wattage rating for my PSU so unless its an issue with the power in my apartment I am lost. 0 other issues with gaming or heat.

Please give any advice how to diagnose or what to do

So there are a few things to check. It is possible your new power supply is not compatible with the gpu, or not actually putting out the wattage they claim, or the connection to your gpu is bad, or its just having issues. Or maybe the new motherboard has a compatibility issue with the gpu or a technical issue with the port. Could need a bios update or maybe a driver update. It could also be overheating due to the change of fans causing poor airflow. Just throwing a few things out there, happy troubleshooting.

I appreciate the thoughts. It was a brand new psu with plenty of extra wattage. My old 750 was sufficient but went bigger just to be sure in this build. I’ll check on bios and drivers. I know my gpu drivers are up to date but not sure on bios. It’s happening with 2 different builds though where the gpu is the only common factor. I feel like that rules out most everything else component-wise

Yeah it sounds like the GPU is likely the issue. Do you have another one you can use for testing?
