Can anyone help me and tell me what is this on motherboard? Only what I can see is written GD. I need to replace this part.
japanchuga that is C583 which is a 1nF 3KV capacitor. No information on the package size available. For that you will have to measure the size of the component.
Slightly different version of your logicboard, but same component on those. Like @automotive said it is important to have the right tools when working at this level. Best tools are some smart tweezers to help you out for the future.
From experience, I’d say it’s a surface mount capacitor. You need to take it out of circuit & measure its value or else get a schematic & look up what ratings it is supposed to have. They are quite cheap to buy, so try getting a new one, as pilfered parts can be difficult to take the solder after removal. Alternatively, measure it using an in-circuit capacitance meter. It looks to be only used for filtering, so I don’t imagine the exact value is critical. If I had to guess, I’d say it’d be around the 100nF mark. Such a part doesn’t usually go faulty, so maybe it just needs a re-work?
