I recently upgraded my pc by adding a 2TB HDD, logitech wave k&m and a 24" monitor. It was running fine for about 2 weeks until it started freezing ALOT and hangs before bios starts. Especially when I restart my computer or press the reset button. The only way to fix it is to turn it off completely, wait a second after everything's stopped spinning and turn it back on.
I've updated my chipset drivers to run the new HDD and have also updated the sata controllers. I've also restored my computer to a few days before the problem started and that hasn't fixed it either.
Have considered updating BIOS (would like to avoid it) as it was hanging before BIOS even started but the flash tools from ASUS aren't 64-bit compatible.
