Problem: My PC stopped showing any displays, the VGA LED was still on, and I couldn't get video back. The keyboard, mouse, and fans were functioning properly. The issue continued even after restarting. It happened while I was browsing YouTube and opening other tabs. I built my own PC and hadn't had any problems before. I haven't installed or updated drivers recently.

What I've tried:
- Resetting the GPU and power connector on both ends
- Resetting RAM
- Resetting CMOS battery
- Disconnecting all devices except the display port and power
- Using a different PCIe slot
- Using a different PCIe power cable
Nothing resolved the problem; I'm stuck with only the VGA LED.

Parts:
MSI Tomahawk B550
Ryzen 5600 (no built-in video)
xfx RX 6650 XT
xpg ADATA Core Reactor 750W PSU
2x xpg 8GB RAM sticks
Running Windows 10

Anything else I should check? I don't have any spare parts. The next step would be getting another GPU?

Welcome to the forums, newcomer!
I built my own PC myself and haven’t faced any issues so far (functioned for three years+).
The PSU I’m using is three years old or newer?
I don’t have any spare parts.
You might want to move your GPU to another system with a solid PSU that can supply 550W and see if the display works. Because of VBIOS UEFI incompatibility, it would be wise to match the donor system’s era with your platform to avoid BIOS issues.
The next option could be getting another GPU?
The best approach is borrowing rather than buying. Purchasing parts for troubleshooting usually leaves you with only a few components, even if one is newer.
Your motherboard has a FlashBIOS button on the back; try flashing the BIOS to see if it restores your display and system performance. This assumes your BIOS has been damaged and your GPU works fine in the donor system.

So the PSU is three years old or older?
- the whole system has been about three years, roughly since around November 2022.
I live in a small city (not in the US), there’s no nearby hardware store parts, and I don’t know anyone to borrow parts from, which is why I’m thinking about buying a new one.
