I recently got a pwercolor 1gb gddr5 HD 7750 to replace my aging nvidia 210..
i uninstalled the drivers for the nvidia card and then switched off the pc and then inserted the new hd 7750..
but after switchin it on i have no display(even though the system seems to be running and the 7750s fan is spinning)

the 7750 has no vga port so im using the dvi to vga converter that came with this card (monitor only has vga..samsung sa100)

i tried disabling the integrated gfx thro the bios and setting the gfx to pcie but no luck

Well, if the only things different in your setup is the video card and the adapter, once you have eliminated the adapter, the only thing else is the video card. What PSU do you have? It is possible that it doesn't have enough "power" to let the new video card work.

Well the psu shoudnt be a problem as its a 450w and the recomended for this card is 400w..going out now to get the adapter

How many DVI ports does the card have? If two, try both.

Make sure it is seated all the way down.

Does the motherboard graphics output work when the card is installed?

You could try resetting the cmos by using the motherboard jumper switch/ taking out the motherboard battery and power cord making sure there is no power then install the card.

Hmm if you think the card is faulty try it in another system if possible. Also if you haven't tried already then update your motherboard drivers/bios to the latest version.

A side note: ensure your psu has enough amperage for your card on the +12v rail.

how exactly do i check if i have enough amperage ?? theres a lot of stuff written on the psu and i cant make sense of it...what exactly should i look for?

UPDATE : i am startin to make sense of it a little..under the +12v it has 9A, 12A, 10A, 12A, 14A, !6A, 17A..is that what im looking for ?

What is the exact make and model of your PSU? Does the PC (& monitor)work with just integrated graphics?

I think its generic(CIL odeysey or some shit)...came with the computer.. its not exactly easy to get all branded items here in india...without the graphic card plugged in...the pc does work with the integrated graphics

I think we have discovered the problem.:( 
I can't find ANY documentation for CIL Odyssey(whatever). it is possible that the PSU has enough Amps to power the integrated graphics(and the Nvidia 210), but not enough to power the 7750.:pfff: 
Can you get a more powerful PSU? What PSU brands can you get?

At this point, it is either a bad PSU or a bad 7750 as the culprit.

Im going to a friends' tommorow to check the graphic card in his rig
if its fine then il have to wait a few days to get the psu...

i can get the Corsair VS450 450 Watt , Cooler Master Thunder 450W , and the cooler master gxII 450w..those 3 are quite affordable at about 60 - 70 $(also the , corsair CX500 & VS500, and thunder 500 if strech the budget a bit but that is all i have left)
are those any good ??
BTW you guys have been really helpful..thanks really appreciate it :)

Of those I would go with one by Corsair over the Cooler Master ones. The VS450shold be enough, but I would go for the cx500, under the theory that you can't have too big a PSU, :D  Just in case you want to overclock or add a more powerful graphics card at some point. ;)

I haven't found any specific info on the VS500, only the VS450. It was highly rated. The CX500 is also well thought of. I would say that whichever on is less expensive would be ok, and serve you well.

Good Luck!

Just because They have the same PSU doesn't mean that your PSU is ok. However, If you can RMA the card, that would certainly be the cheapest way to go, All you spend is time, and it would eliminate the Card as the problem.
If you have the same issues with the new card, then we are back to the PSU.

Good Luck! (hope it is the card.)

@clarkjd
Youre right man..
sent in the card for the replacement anyway and lets hope its turns out to be it..:ange:

il update this after the new one comes in..

And as always...Thanks so much guys
