Will a PCIe card run in a PCU slot?

    Yesterday I installed a hard drive in my computer. The motherboard was out of sata slots so I used an old sata card which I have had for a long time. Back in the day it worked under XP but I cannot find a driver for it, it is just too old I think. The computer is not detecting the new drive.
    A computer shop nearby has a PCIe sata card for a reasonable price, but I only have a PCI slot available, so my question is will a PCIe card run in a PCI slot?

    No! They are not physically compatible in the first place. You cannot insert a PCIe card in a PCI slot without excessive force which will permanently damage the slot. Second, they are not electrically compatible either. Despite their similar names, PCI and PCI Express (PCIe) are totally different interfaces.

    Hi Digerati,
    I thought you would probably say that.
    The hunt for an appropriate PCI card that is compatible with windows 10 goes on ...
