Issue Details

I procured a new PCI card and have been trying to install it in my computer but it does not fit in any of the CPU PCI slots. Why is this happening?


Some motherboards have only PCIe slots.

Check your motherboard to confirm if it has any PCI slots. In case it doesn't, it is recommended that you get an appropriate PCIe card. The image below show various types of slots typically present on a motherboard :
