I'm having a strange problem with this board.

Approximately 25% of the time that I boot up my system the OS hard drive doesn't boot.

There's no LED activity.

I have to turn off my PSU and then turn it back on, then the hard drive boot's up.

I have checked the cables, looked at the SMART values with Speedfan, HD Tune they show the drive as fine.

I also have a fan on the drive, so i don't think it could be heat.

I'm using bios 802, could a bios update to 901 possible fix it.

Anyone have this experience, or a possible solution?
