The Board has the newest BIOS version (0053).
I have changed an external drive. The system was working fine with a WD "My Book" on Firewire. Now I have changed to a new WD "My Book" connected via USB3.0. The system start fails with the message:
The system BIOS has detected unsuccessful POST attempt(s). Possible causes included recent changes to BIOS Performance options or
recent hardware changes. Press 'Y' to enter BIOS Setup or press 'N' to cancel and attempt to boot with previous settings.
I have to disconnected the drive to boot the system. What I have to do for booting with connected drive?
I see exact message. But my system is brand new.
It starts, then show the motherborad skull index page and then restart.
The next time it restarts it shows the unsussful POST attempts screen.
I'm newbie, so everything you talk could be useful to me.
I had the chance to chat with an expert from support.
Unfortunately no concrete hint to solve this problem.
Some points from the chat:
Found a solution -
My PC was not even booting into windows, kept shutting down as soon as i pressed N to the bios message and Y would take me into BIOS Setup.
it was working absolutely fine before going to V0064
Go into Bios
Restore all to Default
And click Performance / Summary
then untick Failsafe Watchdog
must be major bug in the bios v0064
i would try and restore to V0059 im pretty sure this all started after the Visual Bios.
