My PC didn't show any signs of life this morning.
Yesterday it worked normally, I was gaming and relaxing, everything was fine. This morning, when I first turned it on, there was a flash of RGB light in my case but then everything went completely silent. No POST, nothing. The USB port still had power and my phone could charge properly. I tried all possible methods—used a paperclip, changed the PSU, switched RAM slots, removed the GPU, cleared CMOS—but still no indication that my PC was coming back to life.
I have no idea what happened. I've tested everything.
I don't have any spare CPU or mainboard to test parts, so I need to avoid buying replacements for working components.
My PC specifications:
CPU: Ryzen 7 1700
Ram: Apacer NOX 8GB x2 3200mhz
Mainboard: Asrock B450M Pro4-F
BIOS version: P7.40
GPU: MSI RX 6600 Mech 2X 8GB
SSD: WD 240GB
PSU: KENOO Esports E550 550W, new, bought three months ago
OS: Windows 11

if there are no alternatives and you don’t know anyone who can help, reach out to a nearby service provider (like a repair shop or Best Buy) and ask them to check the parts.
