Right now, I have my system running 3.7Ghz stable with mid-30C's and low 80C's on 100% load. When the system goes to sleep for a while, it doesn't wake up. When I move the keyboard & mouse, the motherboard lights up and fan begins to turn, but it doesn't display anything. When I hit reset button, the drive and fans spin 100% throttle for a few seconds, quiets down and nothing happens. The only way to get out of this is 5-second power button cold shutdown. And when it reboots, the BIOS boot-up displays "Overclock Failure" and requires me to go to CMOS and change setting. However, there is no problem with temperature or anything. I've ran Prime 95 for 8 hours without crashing, but it only locks up when trying to recover from deep (?) sleep. Anyone have any ideas? Right now I disabled sleeping and plan to fiddle with APM settings. I have version 1003 BIOS and TRUE HSF (see my sig for more spec) Thanks!
