Windows 7 - I think I turned my video drivers off, how to turn back on?

I need some help, I think I turned my video drivers off and now I need some help getting them back on. A few weeks ago my graphics card failed and some dialogue box showed up and then the computer shut down. Since then I have replaced the card and solved another issue I was having. I can not get the computer to come back now, in normal start up or in any of the safe modes. When I start the computer now I get this:

POST beep
BIOS screen
Loading Operating system
Windows error recovery (with booting options)
The four little dots that come together to form the window with starting windows underneath it.
The screen then goes black I get my cursor arrow and it remains that way until I get pissed and shut it down.

How do I turn these back on and resume normal use of my computer? TIA!

Hi, that usually is some hardware issue, unknown what though. IF Windows won't start run this 3 times: Startup Repair
It might need a Repair Install to get you back too.
