My new graphic card Sapphire AMD Radeon HD5450 2gb DDR3 wont display!

My computer is Compaq Presario(hp) SG3153IL.

Specifications:-
Processor:Intel(R) Core(TM)Duo CPU E4500 @ 2.20GHz 2.20GHz
RAM:1.50 GB
OS: Windows 7 Ultimate 32-bit
Power Supply: 230 Watts

When I connect my (monitor)VGA cable to my built-in (CPU)VGA port it works fine,
But when I install my new graphic card Sapphire HD5450 2gb DDR3 and plug the VGA cable to my Sapphire HD5450 2gb DDR3 VGA port my monitor wont display!

I'm sure that I've seated my graphic card properly and in the correct slot(PCI - E)

I'm very disappointed and very miserable to get a solution or a tip.:(
Thanks in advance,
