Hi guys,
I have been fighting against this issue all the day.
I have a system with:
- Asus Maximus VI Gene
- i7 4770K
- Corsair Hydro H90
- Corsair CMZ16GX3M2A2133C10 Vengeance 16GB (2x8GB) DDR3 2133 Mhz CL10 XMP
- GTX 780 Ti
- PSU Corsair CS750M
- 1 SSD Crucial CT240M500SSD1 240GB
- 1 Seagate Barracuda 1.5TB (from an old system)
- 1 Seagate Barracuda 2TB (from an old system)
With the stock bios (0606) everything works fine, but if I update the BIOS to 1301 or 1203, I get stuck at POST with an A2 code. If I downgrade again to 0606 everything works again.
I have found the problem is with the 2 HDs. With only the SSD connected, the system boots up fine, but when any of them is connected the system stops responding. I tried connecting the HDs to the Intel and ASMedia, but same happens.
I also tried to change the SATA mode to IDE instead of AHCI, and then I get an A3 code.
For the moment, I'm going to downgrade again to 0606 to use it, but any idea about what can be wrong?
Thanks
Edit: All that with only the USB keyboard, and the monitor (an AOC) connected to the 780.
