I just bought a XFX radeon HD 6670. It worked fine for 2 weeks.. Then i had a no-display problem... I checked it in 2 of my friend's computers 3 days each.. They have 250 watts and 350 watts psu. There it is working fine, only I am having problem.. It works some time randomly.. What may be the reason, ? What should i do?

It could be that the PCIe slot is dead. Do you have any other cards that you know work? If so, put them it the same slot as you are trying with the GPU, and see if they work. It the spare card doesn't work, there is a problem with the PCIe slot.
