I have an AsRock H55M-Pro with a core i3-530, running Windows 7 64-bit.
I have 2x2GB of Crucial RAM running in it at the moment (slots A2, B2).
I purchased 2x4GB sticks of Kingston HyperX ram 2400.
My problem is that when I tried to boot my pc with the new ram installed, it did not boot past the boot screen. My keyboard was not functioning (lights were off), therefore I could not load into the BIOS. The PC did not boot past the boot screen, into Windows.
I've read that the ram should default to a safe setting, so I'm a little confused as to why the new ram is not working. I appreciate that I 'do not need ram at 2400' speeds; however it was on offer.
The ram was installed whilst there was no power to the PC and I have also tried to install the ram into both slots A1,B1 and A2,B2.
