Deep Sleep Problem

Hi all,

I've recently built a new system with an Asus F2A85-M LE motherboard and AMD A10-5800K CPU/GPU.

Problem I have is when the system goes into sleep mode, the power light starts blinking but the fans are still running. I then press the power button to 'wake' the system but nothing happens. I then hold the power button in for 5 seconds to stop the blinking, then power it back on - still nothing. The only way I can 'wake' the system is to pull the power from the back and then press the power button to drain any residual power or pull the power and wait 30 seconds, then plug it back in and press the power button and the system will say 'resuming' and go back to where it was up to. So it seems it is actually going into hibernation to hard drive or something rather than a regular sleep. I have turned off hibernation option in the powermodes but it still does it.

Any ideas how I can get it to sleep normally with no fans running and easy wakeup? I'm guessing it could be a BIOS setting too.
