My graphics card is not detected...

I bought a new graphics card for my pc (Sapphire Radeon HD5570) and is not detected by my motherboard.I m running an ASRock conroe1333-d667 motherboard.
I tried so many things to make it work..I formated my pc, I changed settings in BIOS and made PCI-E primmary video adapter, I removed and inserted again the CMOS and still the card is nowhere in the device manager...I also want to say that the graphics card fan is working...plz help me because i m starting getting mad!!!
