My first suspicion here would be that the graphics card was not fully seated. Try again, ensuring that the little catch on the back/bottom/heel of the card engages fully

I updated the BIOS to v01.16. And still same problem . After pluging in the card i press the power on button cpu fans spin everything is powered on but the red light start blinking and the cpu beeps. Monitor says "No Signal". But when i take out the card pc works. Can you help me please? Do i need to do some changes in BIOS?
I tried several time plug in and plug out...

AND cpu z is showing the Graphics interface panel greyed out..

6 beeps indicates (usually) that an expansion card has failed. Is there another computer available to try the graphics card in? It may also be related to a keyboard failure - reinserting your keyboard plug while the machine is off may help. Also, ensure you have no firewire headers occupied by USB cables and vise-versa.
Another possibility is that the PCI slot is bad - that's on the motherboard itself.
