Did you touch or bump anything while looking at the MB and components? Did you shut the system down and disconnect from AC power when you checked the RAM.
Visually check all wiring connections.
Turn off system. Disconnect AC power before doing anything in the case. Depress front power on button to drain residual power from the MB.
Reseat the RAM and check the graphics card connection in PCIe x16 slot. Check supplemental PCIe power connection to the graphics card if it has one. .
Make sure both the 24 pin MB power and 8 pin CPU power connections are correct.
Something connected to the MB needs to be reconnected.
