I think I have the warm-reboot issue as well running at FSB 375, but once I hit the reset button it comes right up. I think my board has other issues though as I can't get Dual Core Center to run and I've exchanged several messages with MSI's tech support about it. I had to tell them three times that the program crashes immediately when it's opened (with a CPU Usage Error(3)!) and that I'm not able to use it at all. MSI tech support sent me bios rev 7.39 (apparently not on their website yet, or wasn't at the time of their response) which didn't seem to fix any of my issues so they said to RMA the board back to the distributor. So I'm RMA'ing the board for a refund as I don't feel like dealing with all the issues this board seems to have. Next up I'll be trying an ASUS P5W DH... we'll see how that one does. It'll be my first ASUS board in... well, a very long time.
