gtx 590 problem
 

i have a gtx 590 and when i played pes 2012 the pc shut down suddenly,and when i try to turn it on again
the fan of the card is 100% and the led of the gtx 590 turned on and turned off . sorry for my bad english

What temperatures is it running at? Try disabling SLI and see if it does the same thing.

the temp is good man but now the card works good

the temp is very good , and it works well

what psu?

Might be the psu crapping out under 3D demand. Does the pc work in 2D mode still and is it crashing when any 3D game played?

my psu is ocz 1000w gold OCZ ZX Series 1000W Power Supply - OCZ ,

i think my psu is very good and can handle any card in the market

when i turn the pc on the , it doesnt start and the nvidia led in the card turned of and turned on

Could be a number of things... no matter how good a part is (ocz aren't known for good psu's as far as I'm aware) it can still die..

I would be looking at PSU, mobo, card in that order (though the card is the easiest to check if you have a spare card / machine)
