Semi-Rebuilt PC has no display

Dear u/Daddy_Spez. OK so here's the situation. Saturday my sata SDD failed. Luckily I was going to be switching to a larger size m.2, unfortunately my old drive died right before I was able to clone it. I was slacking because my m.2 slot is on the bottom of the motherboard and its a SFF build from 6 years ago. Anyways I took everything apart and put it back together. I also upgraded my RAM from 8gb to 16gb but the PC wouldn't boot after I reassembled it. I was able to jump the board with a screwdriver so I decided something went bad on my cases power cords and bought a replacement case which I wanted to do anyways. So I have everything together and the PC powers on fine with the new case power button but I'm not getting any display. I've tried my monitor with the GPU's Displayport and DVI connections and my TV with the HDMI connect (no HDMI on the monitor) I've also tried the HDMI into my TV from motherboard trying to use my i7-7700k's integrated graphics, as well as mb DVI to the monitor and have no display. Does anyone have any ideas?
