I am at my witts end with this problem.
ROG Hero X (Bios 0802)
16gb T-Force 4133
1 x Samsung 960 Pro 512
2 x Samsung 850 256
1 x Samsung 4TB HDD
2 x Nvidia 980
1200 Watt Corsair PSU
All components at stock speeds.
My system is constantly hanging at boot code 4F. I know there is nothing wrong with the individual components as I have had to reinstall windows about 4 times over the last two days, with the system running stable when running. However when I reboot the system the system hangs at code 4F. The only way I got around this was to remove the keyboard, hard reset the system, would boot into a bios safe mode, plug in the keyboard, which would allow the system to start.
However the system now completely refuses to boot beyond the error code.
Now before someone says it could be a keyboard issue, I changed the keyboard same issue.
I have cleared CMOS, at which time it does successfully load the bios but when you exit (whether you change anything or not) the system hangs at code 4f.
I have stripped the system down, inserting components one by one.
I have downgraded the bios.
I have let the computer sit unpowered, with no CMOS battery for three weeks.
I think there may be an issue with the board itself, but any advice would be welcomed.
Thanks in advance
