Issue [RESOLVED ITSELF]



While using the PC, both monitors suddenly lost signal. Restarted PC and then I've noticed a loop in the error codes panel.

The error loop usually shows more 30ish numbers, stopping at the error code 36 or 3b, not sure.. But sometimes, after this 36/3b, I also get 4F. The PC doesn't seem to turn off/boot between loops.

- Tried using a single memory alone, switching memories and slots as well.
- No USBs, peripherals or GPU connected. Only the PSU power cable and sometimes the HDMI.
- The error occurs without my GPU. Tried connecting my TV straight to the motherboard. The error loop happens no matter if there's a video cable connected or not.
- While testing my options, I was able to reach the boot screen, with PC details while using a single memory. But I was not able to replicate it.
- Changed the battery - which was already old (took a couple minutes, which could help resetting BIOS. Didn't work, so I used the Clear CMOS then reinstalled latest BIOS Firmware (renamed it to M6F.CAP. The USB Flashback blinked as expected.
- Noticed that below the Motherboard 24-pin cable, there's a LED flashing red. Not sure if this was already like that and what this means.
