So I am using the MSI Z97 gaming 5 motherboard and MSI GTX 970. I shoved the GPU in the slot, but I'm not exactly sure if it's in. Is the thing at the end of the PCIE slot supposed to lock in place or something? I tried taking it out, but it didn't work, and I am afraid to apply serious force, as the board actually starts to flex. Most likely that means that the GPU is in, but How do I take it out?(I am not very strong as am still a young teenager)Sorry if I am not making much sense, I'm just very stressed at the moment from handling such delicate components.
