GPU card is not fitting in the case

1) Turn off the PC, unplug it, hold the power button, and ground yourself.                                                                              

2) Open side panel, Remove 2-3 metal expansion slot covers at the back of the case, next to the PCIe x16 slot.

3) Align the GPU's connector with the motherboard slot and its metal bracket with the case opening. 

 4) Push straight down with even pressure until it clicks. DO NOT FORCE IT! If it resists, something is still wrong. Recheck alignment. 

5) Screw the GPU's bracket into the case and connect all required PCIe power cables from your power supply to the GPU.
