You have to check the card in a different system to isolate the cause. Seems like 2 options, card gone bad or PSU not good enough.
 
Ensure ur Card is fitted in firmly, the lock at the right side should have clicked in. Also have u connected the 6 pin power connector to the card?
 
I think ATI 4850 consumes lot of power and Zebronics 550W will not be enuff for ATI 4850..

Thats my opinion and i am noob

Wait for some more suggestions from experts :p..

I doubt it since I am running a Sapphire 4850 on my CM Real Power 450W. And it's fine.:)
It can be due to overheating or a faulty PSU.
Alex,check your card in some other system and see if it works fine or not.
 
Cooler Master real power 460 gives upto 550W:p
@Alexcochin Be more specific about the problem.Explain in detail.Your PSU is good enough for the current configuration.
