So I just got a new case and RAM. I moved the parts from my old case to new and replaced the RAM, and now my computer stays on, but the displays will not turn on or show up with anything. Also, for some reason my graphics card won't fit into the PCIe slot so I just left it out of my case and plugged the dvi cable from my monitor to the port on my motherboard.

reset the bios.
Your system is set up to display off the GFX card, but now your GFX card is not in the system. Check the BIOS and make sure that it is set to use the on board GFX instead of the discreet card.
