The ram right now are in slot 1-3 and I'm using the Corsairs 1066, now all I did is change the voltage in the bios from 1.9 to 2.2 and also there is a option there were is default at auto I changed it to 333/1066 and saved it. Now whats wierd is when I try to turn on the computer from the power button on the case it just does the same old story C1 and shuts down... I need to press the power button inside and hold down the DEL key in order to get the system to boot!
