It may not be "missing", it may just be unneeded. Does the card work? If yes, don't worry about it.

Many boards can serve different purposes - different ram, clocks... and may or not populate parts of the board as they are not needed.Memory chips, additional capacitance....

Hello, thank you for your quick answer, the video card is not working, that card came from another country in a case which had 2 loose hdd, so it may be that the capacitor droped by a hit.

OOps - in that case many switching regulators will not work properly without the input or output caps. Did you find any pieces in the case?

Without having the schematic to know what capacitance value C919 is will be a guess. It looks like a larger value ceramic possibly 1- 10 uF - they are not expensive but again, only a guess. Caps this size can be soldered on by using a temp controlled solder iron - do not have to have hot air rework.
