Help with drivers for GT 730 pci-e x1 in an old Dimension E310

Well, I finally found a Zotac GT 730 pci-e x1 1gb video card online.  Had to buy used as no one has it new anywhere being outdated etc.  The E310 has no pci-e x16 slots so this was my only option besides std pci.  Of course I was not provided any driver cd, etc., but figured I could get at the website which I did... twice.  Unable to get the drivers to be recognized, etc. and have contacted Zotac to see what other options I have... getting a driver cd from them, etc.  Any other suggestions on what I can do.  With other cards in the past I have had to do this from time to time and usually no issues.  One more thing I forgot to add.  Both times that I restarted my comp. after driver download was complete, it froze at the windows starting screen.  This only started happening after I did the driver download.  I did just now get the install of the driver to succeed and in the device manager it now shows the GT 730 named with the yellow exclamation point stating I need to restart for the video card to function properly.  I restart, and back to the frozen start up, have to restart f8 to last successful point, and video card no longer recognized.
