Question Clicked a RAM stick into place while PC was off

[NinjaToothpick]

My friend realized her PC was only detecting one stick of ram so she turned her PC off and clicked one of the sticks into place since it wasn't fully in since she installed them. Now all she has is a black screen when she boots up. I've done some builds before but I'm no genius with troubleshooting anyone able to help with this ?

Please share the specs to your friend's build like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Are the rams, from a kit? If so, please make sure that wile on the single stick of ram, to go into BIOS and see which version of the BIOS is on the motherboard. If you have updates pending, update them.

Also which slots have you populated on the board?
