[SOLVED] New ram, no display signal!

[pyro2195]

After upgrading my RAM I'm not getting any signal from any of the display ports not even post bios. the motherboard indicator turns on, the fans spin up, the hard drives spin up. I've placed the original ram back in and it works fine, put the new ram in and it doesn't work.

Original ram: 4 sticks
2x 2gb Kingston kvr800d2/2gr
1x 2gb Kingston kvr667d2n5/2g
1x 1gb Samsung m378t2953-ce6

New ram:
4x 4gb Samsung M378T5263AZ3-CF7

Motherboard: Asus m4a785-m

Processor: AMD Phenom2 x4 940 3ghz Quad core

OS: 64bit Windows 7

Any help please and thanks in advance for your time!

Mixing RAM like that is not a good idea, it usually doesn't come to any good.

Combining DDR2 memory modules sold as Singles may not be compatible together in multiples. I suggest you return them and use a single kit.

Reset the BIOS.
