Issue: Periodically whenever I reboot my machine, or cold boot it, I run into an issue where the boot code stops at error D6.
- Last 3 code sequence: 98 > 99 > D6
- LED Sequence: White > White > White and Green
The screens never turn on and the machine does appear to be booted. I can confirm this because if I wait long enough, I can hit the space bar, enter my password, hit enter, and then any RGB lighting will turn red indicating that the RGB software is running.
Eventually after hard booting several times, and holding the Clear CMOS button, the system will post correcting and my screens will work. I experience no issues when everything is working as intended. If I restart my machine or turn it off, there is no guarantee it will work again without trying multiple troublshooting steps.
I have performed the following steps:
- Turned the machine off and on again
- Cleared the CMOS
- Updated the BIOS
- Updated all firmware
- Updated all drivers
- Reseated GPU
- Reseated RAM
- Ensured all power cables are connected properly to motherboard and devices (no extension cables)
- Updated DisplayPort cables ensuring they support the correct resolution and frequency
- Disabled XMP
I have had these issues intermittently since configuring the PC and have not been able to determine the root cause. None of the troubleshooting has resulted in a permanent fix.
