Computer hangs after installing new graphics card

Long story short - I recently bought a new graphics card but when I put it in the computer hangs at the Acer splash screen, the keyboard does not work, it beeps 3 times (short beeps but they are very far apart), and then it goes to a black screen that sometimes has a flashing cursor in the corner.  If I put the old video card back in it works fine. I can't even get into BIOS with the new card installed. The new card works perfectly on my friends computer.

 

If someone could tell me how/where to post this question properly in the community, I will add all my computer specs.

My computer is an Aspire M3450 running Windows 7.  It has an AMD FX-4100 Quad-Core Processor and a new Corsair CX750 PSU.  The old graphics card, which still works perfectly, is a Nvidia GeForce GT 520M.

 

The new graphics card is a Nvidia Geforce GT 730.  As I said before, when I plug in this new graphics card the computer turns on, I get to the Acer splash screen and then nothing happens.  I can't get into BIOS because the moment I touch a key on the keyboard the light goes off and it stops registering.  After a few seconds the computer beeps, waits a few seconds and beeps again, then a third time.  Then the screen goes black.  The last time I tried there was a flashing cursor was in the top left corner.  This was not there the times I had tried previously.

 

I have tried the new card in a different computer and it worked fine. I uninstalled the old video drivers before inserting the new card. I have even tried telling BIOS to use the onboard card while the new card is plugged in.  This works fine and the computer even automatically downloaded and installed the drivers for the new graphics card.  I shut down, went back into BIOS, told it to read the PCI video card instead of the onboard card, and when it restarted after saving the changes it went back to sitting at the splash screen.

 

Anyone have any ideas?
