No display after new NVIDIA GT 730 (2GB) DDR 5 graphics card

My pc is running windows 7 - 64 bit ultimate. I upgraded the motherboard of my PC in 2010 with second generation i3 processor and 4GB RAM. It has integrated intel graphics already.
Today I installed new Kingston DDR3 – 4GB RAM. My pc has detected it and running fine.

I also installed ZOTAC NVIDIA GT 730 (2GB) DDR5 Graphics Card in its PCI slot.

Unfortunately, when I turn my PC on, the monitor goes in power save mode. The graphic card fan runs smoothly.

I tried the following methods with the graphic card still properly attached within my mother board
1. My monitor connected to the graphic card via VGA cable. Nothing happened
2. My monitor connected to the graphic card via HDMI cable. Nothing happened.
3. My monitor connected to the original old slot (it works fine) through VGA cable. Nothing happened.

However, if I remove my graphic card, my PC runs fine. What should I do? I am running SMPS of 450 W. Upon confirming with my friend, he said that I should use 800-900W to run my graphics card. To my surprise on their official website, Geforce has listed minimum power requirements for my graphic card as 300W.

I don’t think that my graphics card is damaged as I bought it from Amazon. I have bought lots of electronics and delicate items from that site and have never received damaged product.

Yes, it was shipped and sold by amazon.




It does not have any extra place to draw power. I l also tried to change my bios settings to select PCI slot first for graphics card in case of first preference, but I cannot find the option unlike seen in south bridge field.

What computer do you have? Did you disable on-board video? Have you installed the drivers?

This is my motherboard information.

How to disable on board video?

I did not install nvidia drivers because my pc is practically not running after I insert the card in the motherboard. Shall I install drivers first without the nvidia graphics card inserted, shut down my pc, insert graphics card and start it again?

on-board video settings should be in the bios.

I could not find such option.



You can see in my first BIOS photograph that auto detect dimm PCI clk is enabled. Does that mean my motherboard is set to automatically detect new graphics card when they are inserted in PCI slot?
