Asus P5K Premium, Vista, and power saving

[ssilverm]

I'm using 64-bit Vista Home It had been running for almost a year on a Gigabyte GA-P35-DS3R motherboard with no problems. That board died so I replaced it with an Asus P5K Premium, and carried out a fresh installation of Vista. Since then I have been unable to put the PC into sleep mode, either by using the power options or by forcing it to sleep with the relevant command from the start menu. I get lots of disk activity, but the computer remains resolutely awake.

Any and all ideas gratefully received.

I have and identical situation, running a GA-EP35-DS3R though.. Vista x64 Ultimate. When I select the sleep mode, monitors go blank but everything else is still running and the HDD is running too. Hope someone has a solution for that
