Hero post code "02" from ROG Crosshair VIII on an old machine
Constructed the device around two years prior. All components are original except the GPU, which was upgraded from a 1070ti a few months back. I've faced no problems until recently when it started displaying "02" and "OC" and refused to start. It has randomly restarted twice while this issue persisted. Notably, after replacing the GPU with an older 1050ti yesterday, it booted successfully, but switching back to my 3090 once more resulted in a stable run today—though it’s now returning to the "02" error each time I try to power it up. CMOS battery reset didn’t help. According to sources, the "02" code often points to display problems, so I’ve tested multiple display cables and HDMI connections without success. Any advice or next steps would be invaluable. Specs: Mobo Asus Crosshair VIII Hero CPU 3900x @4.5 Ghz, Zotac 3090 RAM 32GB, Corsair Vengeance
This code usually connects to VGA problems, but it might also indicate a fault with the graphics card itself. A corrupted BIOS could be the issue.
