OK...By wouldnt enter OS I mean the PC will startup but it wont even go to BIOS (should have been more specific sorry)

Yes i had 3x2gb now I want to install 3x4gb

The original RAM kit was rated at 1.65v and the new ones are 1.5v.

As far as resetting the CMOS I have tried both resetting to default values from BIOS and then installing new RAM with no results as well as removing the CMOS battery and installing the new RAM, also yielded no results.
