Q-code 33
Q-code 33
When the system powers on, the motherboard displays code 33 indicating a CPU POST-MEMORY INITIALIZATION ERROR. I attempted all standard fixes—re-seating the CPU and reinstalling RAM—but the issue persists. A peculiar noise is heard from the PC, sounding like a high-pitched scraping. When this noise becomes erratic, games freeze because no sound is being processed by the motherboard. Additionally, the latest BIOS has been installed.
Viewed the video but heard nothing except the CPU fan. There were occasional clicks, likely from the person operating the system and possibly coming from the floor or another source.
It's a high-pitched noise, clearly present, but my goal is explaining that stopping the sound causes the computer to freeze.
I discovered it's a VRM coil noise issue. Occasionally it fluctuates and the computer freezes briefly—about half a second—three to five times when audio plays.
It's strange, I'm facing the same issue—Code 33. With Aorus Master x570 and Ryzen 5900x/2600x. I'm curious if the thermal paste in the CPU socket and any extra material pushed into the holes are causing this. I'm currently using Thermal Grizzly's Kryonaut. I'm thinking about soaking the board in 97% isopropyl alcohol and then using a powered duster to dry it. Will post updates later!
