I have an ECS G41T-M7 and everything works great, including ethernet and audio. All, except for sleep, my worst enemy. Putting the computer to sleep properly shuts the system down (no fans or drives on). However, waking the system results in a black screen. If anyone is willing and able to help me solve my issue, I would greatly appreciate it.

My Setup
CPU: Intel Core 2 Duo E8400 3.0GHz
Memory: PNY 8GB (2x4GB) DDR3 PC3-10666
Video: AMD Radeon 5750 1GB

I would like to make this machine into a media server, but without sleep working, it seems kind of pointless to me.

I suspect my sleep/wake issue might have something to do with the fact that my board has an ICH7 chipset that does not support AHCI on SATA. Can anyone out there confirm this? Know a fix?

After some more research it seems that Repost Video on S3 Resume might be causing my wake troubles. Only problem is that the bios on this board has no such option to toggle it on/off. Anyone know any solutions to this? Thanks.
