Hi guys

Just finished my build with new cpu, MB and memory must say am really please with the performance, having an issue when my pc goes to sleep it powers off ok though when I press the mouse button or a key press on the keyboard the main systems wakes up though the monitor stays in the powered off state,

I then have to hold the power button on the main case and restart to the the sytem to get the monitor back on

Ok it would seem to be an issue with the Bios though the board has the latest V installed, I suppose I will have to put up with it

In the bios, is there a "re post video on s3 resume" or similar option? I have this on a couple of boards im using and assume that it is for exactly this problem?
