This may not be the problem but the recommended power supply is 500W for the gpu, you do have a 550W PSU, maybe not enough electricity the GPU? What was the guys PSU Wattage when you were watching him fix the problem?
Even with the extra Wattage needed for the signal of the Sound System you got. Also possibly Extra Wattage to the GPU since you got a 4K monitor. The HDMI signals do need power so maybe running a 4K HDMI Cable with a Sound System requires more power. I do not know if this is the problem but if this solution fixes it then you're welcome, but I could be possibly wrong.
According to this website
AMD Ryzen 5 2600 Review > Power Consumption - TechSpot
your Ryzen 5 2600x can draw up to 370W under load. But that says SYSTEM POWER CONSUMPTION meaning the CPU, Motherboard, and Possibly RAM.
The CPU is consuming ALONE is taking ~78W which means if you read more into my discussion as to why it might be ur PSU CPU(78W)+GPU(185W)+MB(166) = 429W
So maybe you having a 550W power supply is not bad but if you look at other Computer youtubers they run Higher PSU Wattages to prevent low power being delivered to the GPU because the CPU is taking up lots of it and the Motherboard too.
The GPU is consuming 185W
So, 370W + 185W = 555W assuming both are under max load.
You're motherboard is consuming 40.8W idle and 166.2W load power consumption.
With the Motherboard added that is 721W under load for the CPU, GPU, and Motherboard. You're PSU is 550W.
I MAY BE WRONG, like I would rather have some more experienced and more better at this stuff than me. I'm just writing a whole paragraph on why it might be your PSU. So, if you think about it, getting high performance things like your GPU, CPU, and Motherboard, they require lots of power as you see, AND you STILL need EXTRA power for the SSD, Hard Drives, RAM, and FANS. They may not draw lots of power BUT you still need to think about those things, you can't just go and buy a 500W PSU just because the Specs of the GPU said so. Before buying components you need to see what type of PSU you need by adding up the MAX power consumption of each component if you plan on doing that like running at 4K maybe 60fps or 144fps and with a Home Theater Sound System. I'm not saying you're going to be running every component at MAX power consumption, it's just you need to be ready for these occasions.
This is why is could be possibly you're PSU. I could very be possibly wrong. It may be a Driver issue for your Green Screen. Even though u tried doing things to the drivers.
Hey llvewire, I ran OCCT and I'm trying to check my GPU power usage but it doesn't seem to show it. All it shows is the CPU usage, as shown in the image I attached here. I checked settings but there's nothing in there to show anything else. Am I doing something wrong?
