Ya i would have to agree..incorrect drivers are most common. i've had my own nightmare as of late. just put togeather my new server box a few days ago and i was getting reboots every few hours sometimes even a bluescreen. the long beeps at bootup made my think it was faulty ram.. then i
finally noticed the big question mark sitting next to my raid controller in the device mang. appearently windows installed it for me, with the wrong freaking driver. fixed now, and have been up for 10 hrs and 11mins w/out a reboot!!!
