Speaking of PCI, in fact, the slot where the graphics card is inserted in your chassis is the PCI slot. This slot has different numbers according to the model of the motherboard. To be clear, some graphics cards need an external power supply. Did the landlord check whether the external power supply of his graphics card is loose, resulting in insufficient voltage stability? In this way, the graphics card works normally, but when using the GPU graphics card to preview the video effect, there will be some stuck, serious crashes, PCI errors and other phenomena.

Second, check your PCI card slot to see if there are other incompatible device cards such as acquisition cards.

Third, the landlord can check whether the dust exceeds the standard and wipe the gold finger of each PCI card.

I hope it helps you.
