Screen goes dark instantly, GPU spins fast, and then sound issues appear.
This issue has been occurring often lately. My actions—such as downloading files, launching new projects, or playing games—can trigger it. Suddenly the screen turns black, the GPU halts HDMI output, fans spin fast, and any audio stops with glitches. The GPU and motherboard lights stay on. Each time it happens, I must press the power button to restart and turn it back on. It keeps repeating.

You may be running low on power and require a replacement PSU. What model do you currently have?

FSP SFX Pro 450W American Megatrends Inc. priced at $2.40 on 11/2/2015 aims to refresh the BIOS soon.
You might be experiencing a failing PSU. My previous unit was likely to cause similar problems. The only variation is that my GPU fans stopped spinning completely. I swapped out the GPU but the issue persisted. I upgraded to a Toughpower PF1 750W and it resolved the problem entirely.
You've managed to keep the PC running for a week, but the screen now has less consistent performance. Occasional blackouts occur, especially when using Blender or Unreal Engine, and the GPU fans spin hard during intense rendering tasks like Cycles mode. To prevent this, consider optimizing your workflow, adjusting settings, and monitoring system resources.
It seems the updates aren't helping, the power supply upgrade didn't make a difference, and I'm not excited about getting more equipment.
