PC Shutting down during a game.

[Daniel Francis]

Hey Guys

So recently i finished creating a new build into an Alienware Area 51 Chassis.
Ive been trying to play Assassins Creed 4, at about 10 minutes into the game, it will instantly shut down like its over heating. and turn itself back on.

Ive got HW monitor up on a second monitor and my CPU level isnt going about 35 degrees, and my GPU gets to around 75 degrees.

Are these bad temperatures? My graphics card MSI GTX 780 starts to make a squeal noise, its not too loud but loud enough, but ive heard that is coil whine? nothing to worry about? correct me if im wrong, im just going off things ive heard around places. Could it be a problem with the GPU?

Ill attach a picture so you guys can see the inside of my machine, atleast to get an idea to see if its really awful air flow or something

What power supply do you have? Those unsleeved cables lead me to believe it is likely one of the cheaper ones and you might not have enough power to run a 780 for extended periods of time.

its a dell power supply that came with the Alienware case. its 1000w. Does that mean its still not good enough?

Also what about the whining noise the card is making? is that an issue?
