I am an impatient and stubborn person, so here is what happens usually.

Step 1 - I usually lose once or twice. No big deal, just start over try it again.

Step 2 - I start to die more. Anger bubbles slightly inside of me.

Step 3 - I die a lot more and I start to grit my teeth, start to swear, and say or variations of the following: "Oh my god" "for *insert swear or messiah here"'s sake" "AAAAH!"

Step 4 - I die so much more that I quit playing in blind fury and be an overall bastard to all existence for the remainder of the day.

I can't really get mad at a video game.

Hell, I can't really get mad at anything. I can get annoyed sometimes, but that's about it.

Video games don't stress me much.  I play too much poker to get mad at dying in a video game.  Stress is staring at $150 in the pot, trips in your hand, and a possible flush on the board, lol.

i just stop playing.... give it a day or two and try it again

I play videogames to relieve stress.

MM i never stress myself on non-online games, i just get stressed when i am playing competitive online games and make stupid mistakes (mostrly on rts), still its my favorite kind of games xD, most times I curse and other less i punch something nearby but not so hard just to release some energy =) and that would do it

i just smoke a fat ass joint. and get back to gaming

I kill the boss/dude.

I put in another game or do something else for a while.

If you get mad at playing a video game, you got issues. Its fake, its not real, its not even worth getting mad over. Hence, thats why its just a game. You don't have to play it.
