Original Specifications CPU: AMD Ryzen 7 7800X3D at 4.2 GHz, 8-Core Processor (sold by a trusted eBay vendor)
CPU Cooler: Thermalright Peerless Assassin 120 SE with 66.17 CFM airflow
Motherboard: MSI MAG X670E TOMAHAWK WIFI ATX AM5 (refurbished by another reputable eBay seller)
Memory: TEAMGROUP T-Force Delta RGB, 32 GB (2 x 16 GB), DDR5-6400 CL32
Storage: Samsung 990 Pro Video Card
GPU: XFX Speedster MERC 310 Radeon RX 7900 XT, 20 GB RAM
Power Supply: EVGA SuperNOVA 850 G+, 850 W, 80+ Gold Certified, fully modular ATX
I encountered a red CPU indicator while attempting to fix graphics problems. I swapped the GPU, used DDU to remove drivers, but the issue persisted. Here’s what I tried:

- Reinserted the old GPU and saw the red light.
- Removed RAM, SSD, still got the red light.
- Cleared CMOS by shorting pins as per manual.
- Removed CPU, cleaned thermal paste, reinserted, but red light remained.
- Plugged back in PCs on different outlets—still no change.
- Used BIOS flasher; bios update completed but red light stayed.
- Checked power cables, ensured correct orientation, still no improvement.
- Applied a power cycle trick by flipping PSU switch on/off.
- Tested with a different motherboard on Amazon to verify if the problem was hardware-related.

Despite thorough checks, the CPU kept flashing red. I suspect either the refurbished board had a defect or I made an error during installation. The RAM light disappeared only when plugged in, suggesting it wasn’t the main issue.

I’m seeking advice on next steps—didn’t redo troubleshooting fully. Could the motherboard itself be faulty? I considered buying a new one to rule out the refurbished unit. Anyone have suggestions or alternative solutions?

I’m facing the same problem you mentioned! Have you discovered a fix yet? I upgraded my graphics card and that’s when the issue began. The PC was running smoothly before, but now the red LED won’t stop lighting up. I even tried using the old card again, but it won’t open the BIOS.
