Please excuse this silly question but you did switch the monitor signal plug over to the new socket didn't you? Yeah, I know, but sometimes this obvious step has been overlooked.

Otherwise go into BIOS and make see if there is anything you need to disable/enable there, in terms of on-board and/or add-on graphics.

You are likely to need drivers for the new card.

Always pop back and let us know the outcome - thanks

Are you sure your PSU (SMPS in India) is powerful enough? Did you connect the 6-pin PCIe plug to the card?

did you connect monitor cable to new video card or check bios to see if anything needed able or disabled in bios?

Are you using a 6 pin adapter or an actual 6 pin connector from the power supply. As riider implied, power supplies sold in India are usually substandard.

What processor are you running?

Be sure the graphics card is fully seated. Do not mess with it until you unplug the computer.

What port are you using on the card? Are you using any adapters between the monitor and the card?

With the card plugged in (but giving no output) does the on-board port work or do neither work?

If you are using a two four pin molex to 6 pin adapter, you must make sure that you use the connector on two 4 pin molex connectors on two different wire runs or you will not be dividing the load evenly on multiple 12volt rails since on most cheaper power supplies with multiple 12 volt rails cannot handle the graphics card on a single rail.

If you reconnect the onboard graphics (remove the graphics card if needed) and go into your BIOS set up see what option you have as far as graphics set up is concerned. You would be best if there is a setting "use onboard graphics if no other graphics cards are present" (or similar), if there is, then use it. If there is an option for graphics source then you might have a drop down with options like PCI, PCIe 16x, and possibly others, use PCIe 16x or PCIe if that is an option (if ther are multiple PCIe options, choose the one with the highest multiplier and the first of them where applicable). If you are confused by it post the options back for further advice.

You have to be a little bit crazy to keep you from going insane.
