Recently I built a system using a DH67GD with an i3 2100 / 8G 1333 RAM as an entertainment unit. I installed Windows 7 64bit SP1, then installed all the latest drivers from the Intel site.
That all worked great, I did various CPU and RAM tests and it all looked fine.
Then I installed my aging PCI Xonar D2/PM, and now the system won't automatically enter sleep mode. It'll do so from the Start menu/Sleep command, but not from the timer in Power Management. The sound card itself works properly, as does the rest of the system, just no automatic sleeping.
I used the Xonar Unified Drivers 1.41 which are modified from the Asus 1794 drivers, and I guess someone will tell me to uninstall them and use the official Asus drivers. I'm wondering though, if the inability to automatically sleep is a PCI bus issue that keeps the system awake.
The next step I guess is to remove the Xonar, install a PCI NIC (for axample) and see what happens, but I thought I'd ask first. I also seem to have had issues with power managment in every version of Windows that I've ever used (all of them...) so it may be that.
Any help appreciated
Try to get the latest BIOS as it has some changes in regards the PCI latency timer, hopefully that will fix the no-sleep situation. You can get it on the following link:
