The ROG X670E HERO motherboard's start light is active yet inactive.
PC Build details have been shared. The system runs an AMD 7950x3D CPU with an AIO Corsair H150i cooling solution, paired with an Nvidia RTX 4090 GPU. Powered by a 1200W Thermaltake PSU and equipped with the ROG CROSSHAIR X670E HERO motherboard. Memory consists of two GSKill 32GB DDR5 sticks at 6000MHz CL36.
The user reports persistent performance issues over nearly a year and a half, noting high memory usage in Task Manager while CPU activity remains low. Recent restarts triggered freezing and error codes (45, 15, 10, C5). Booting is now impossible despite lights on the motherboard and keyboard. Several troubleshooting steps have been attempted without success: re-seating GPU, swapping to an older model, inserting no RAM, adjusting CMOS, removing panel cables, updating BIOS via USB, testing alternative RAM, and trying a different motherboard.
The user seeks advice on potential causes or further tests, suggesting prioritizing RAM replacement and PSU upgrade before considering hardware upgrades. Assistance is appreciated.
Power supply: 1200W Thermaltake
Thermaltake represents the brand, and 1200W is the stated power output. What model does this device have? If this power source has been used before, how recent is the unit?

Rams are placed in slots A2 and B2, and are fully seated in those slots.
Inspect the CPU's socket for any bent or broken pins and reinsert the CPU with the AIO's cooling block resting on the processor's IHS, which means you need to position the case on its side rather than upright.
I installed the latest BIOS onto a USB drive, but it shouldn't matter until my system is ready.
For clarity, which BIOS version were you attempting to flash?
The PSU matches the build age (about a year and a half). The model is Thermaltake Toughpower GF3 1200W 80 PLUS GOLD. RAM is in A2 and B2, but I've been testing in just A2 or B2. I haven't checked if the CPU is bent because I don't have thermal paste to re-seat the AIO. There hasn't been any BIOS flashing, so no updates have been applied. The USB drive I have is version 2403. Should I skip newer BIOS updates and start with the oldest?
I would attempt to update the BIOS using 2505; we'll be back.

Your processor includes an iGPU—try working without the separate graphics card and see if it improves performance. You may need to obtain thermal paste quickly to confirm the issue isn't with your motherboard, allowing you to start an RMA.
