Question 3080 RTX Intel I9 Computers keeps black screening randomly

[Pyrrhus2579]

So I recently bought a computer from cyberpowerpc. It's a Nvidia GTX 3080, Intel Core I9 11900KF Z590 Pro Wifi (MS-7D09) and unfortunately it hasn't been working properly since receiving it. It'll play games, look beautiful, but randomly during games the screen will turn black and search for an input, before finally saying no source found. I have to restart it after that. I've tried reseating the GPU, applying a better CPU thermal paste to it, added a few fans out of fear of it overheating, updated the bios, tried a system reset. Uninstalled and reinstalled the GPU Drivers. Nothing has made an improvement, or even a dent. Switched to high performance power option.

Not sure of an easy way to post my entire system specs, or the reliability history, although I do have that in a XML file.

What is the exact psu, make and model?

Have you contacted Cyberpower, this is where you should use the warranty.

Sorry for the late reply, I literally had to hunt down what sort of PSU it was. It's a
PS-119-115 APEVIA 1000WATT GOLD 80 PLUS POWER SUPPLY
