Hey guys, after a couple years with my system running on an Asus P6TD Deluxe, I had an opportunity to pick up this motherboard brand new for 100 bucks. So I rebuilt my system withthis board with some really high hopes. Everything loaded up fine, grabbed the latest bios and drivers and was all set to start OCing. However, I noticed an issue with the S3 sleep state that is slightly different than what people have described in this thread.
The system has the following: Win 7 64 bit with all updates. Corsair 1600 Mhz memory, Core i7 950 liquid cooled, seasonic 750 power supply, 2 X 6950s, 2 X SSDs, 2 X WD Black 500 GBs, 1 TB Seagate, and two optical drives. Just built and everything at stock still.
Everything runs fine but I discovered one interesting issue that I can't seem to resolve. If the PC either goes to sleep (S3 state), or if I put it to sleep, it will restart fine and run properly again. However, after going to sleep and waking up, the PC will no longer shut down properly. Instead, it will get to a point where the screen goes blank, but everything else remains on. The power light AND the HD light are solid red. The only way I can get it to power down after this, is to either hold the power buton or cut the power at the supply.
I have now tried the following with the Intel SSD and a regular 7200 RPM drive on both the Intel and the Marvel sata controller without any change in results. I have loaded Win 7 fresh and only added the video driver (in order to enable sleep state). I have set memory to 800 mhz, and added nothing else to Windows. It isn't the video drivers or the video cards because the system on my asus board went to sleep flawlessly.
If I put it to sleep in the S1 state (which is useless) or hibernate it, the issue does not occur. Only going into and coming out of S3 sleep.
Any help would be appreciated because I simply don't know what else to try.
