Need a bit of direction

[kneedeep]

I'm replacing caps on a video card. Each spot for the eight I need to replace has one side marked by a white (nearly) half circle. I'm thinking they indicate polarity but can't tell if it would be indicating the positive or the negative pole.
Is there some standard for these marks or must I find specifics about the board itself?
The new caps have a gold band on one side with an outline of a rectangle which would seem to indicate negative but I'm only guessing.
See the attached pic.
If you can't tell this is my first attempt at replacing bad caps.

Opps, sorry I had to edit that.

The white marking (half circle) on the pcb board usually indicates negative pole (I just found a motherboard with the opposite that's the reason for the edit.)
You are right about the capacitors, the gold marking side is negative, you can see small minus signs on them.

Before you remove caps, it's good practice just to take a look of the polarity before removing them.

Bar indicates negative side.
Some manufacturers however (Asus and Asrock for example) use bar for positive side. Check once for every board, the layout should be consistent on a board.

On that board, the silkscreen is a bit weird because they overlayed two silkscreens, just in case they were going to switch from one capacitor brand to another that had different diameter.

Note that in the corner, that's no capacitor footprint, that's a footprint for an inductor, that's why there's no white silkscreen bar. Don't have to fill that space and the two capacitor spaces anyway, seems to be a whole dc-dc converter optional there.

Thanks for the reply guys.
Truth is, I didn't even think about polarity until I was beginning to replace the bad caps.
@Mariushm I wouldn't know a capacitor footprint from a hole in the ground. LOL
Anyway, I've got them in place and tomorrow I'll get the card installed and see how I've done.

Thanks for the help/advice.
