Earlier today I booted up my computer and noticed the Nvidia control panel wasn't an option on the right click context menu. After going to services.msc, I noticed the Nvidia display driver service wasn't running, and if I tried to start it, it would immediately crash. I then went to device manager, and saw that under Display Adapters, the only visible one was Intel Integrated Graphics. I wiped the Nvidia drivers, and when I tried installing the latest ones I was told that "This graphics driver could not find compatible graphics hardware." I also tried installing the drivers from the lenovo support website, which yielded the same error. I've already tried resetting BIOS, which did nothing. My concern here is that either the graphics card has died, or it has been shaken out of place somehow. Are there any suggestions you can offer to fix this, or will I have to take apart the laptop? Thanks for your help.
Specs:
CPU: Intel (R) Core (TM) i5-4200U @ 1.60GHz (4 CPUs), ~2.3GHz
RAM: 4GB (4096 MB)
GPU: Intel Integrated Graphics (Onboard), Nvidia Geforce GT 720M (Discrete)
OS: Windows 8.1 64-bit
Model: Lenovo Flex 14

If it is not detecting the video card it is possible that it has been moved out of place. The other possibility like you said, it could be a dead video card.
If you haven't already checked BIOS to see if it is loading the video card first, and not the integrated graphics, you may have to check to see inside the laptop if the video card is properly installed. If you don't feel comfortable taking apart the laptop you could always take it in to have someone else repair it.

The BIOS gives me the options to boot with Optimus or UMA only, which I understand to be only onboard graphics. I guess this means I'll have to take it apart and check it out myself. I'll report back once I get the chance to do this.

In the end, it was a corrupt driver that was messing everything up. Uninstalling "Intel(R) 8 Series PCI Express Root #5" in Device Manager cleared up all the issues I was having.
