I updated to the new BIOS, which went form P1.1 to P1.3, yet the problem still persists. It will show the ASROCK logo and go through that part of the boot, but then gets stuck at the IDE initialization, and stays at the blinking underscore screen indefinitely. My Debug LED says its initializing IDE, but will not get past that. Also, at that stage my restart button no longer works, and the CAPS LOCK, etc. keys on my keyboard don't affect the LED indicators anymore. I know the system's hung, but I always thought that unstability was a gradual thing, and not a cutoff at a specific Hz. I also thought the more voltage applied the higher the overclock, yet no matter how much I throw at it (1.5V once) it will not boot Windows 7. Oddly enough, my 4.3 GHz clock will boot no problem and pass Prime95 on only 1.25V and 53C. Did I just get a weird chip or mobo?
