7900GT "dead" ?!

You could use them to test if your board is still O.K.
But you have to be a little inventive since the gate is on the left side and your board expects the gate to be on the right side.
The single source pin is on the right side and is expected to be on the three left pins on your board.
But for a quick experiment they are very usable. If everything works as it should, you can always switch them for the IRF7821.

ok i get flytek's description.... with the silver plane and the others grounded.

i cant understand your post,

well problem is i cant understand how the mosfet should be soldered on, which pin where, you know.

if i understand correct its like this?!

broken mosfet:
red ones are ground
blue one i dunno = silver plane
yellow one = dunno

do you mean the one side of the mosfet IRLR7821 with one broad pin (gate?) should be connected to the silver plate? (blue ones of the broken?)

but which of the other ones goes the the 3 red ones (on broken one)? the green or the red of the IRLR7821,

and whats about the yellow one on the broken mosfet and the blue short one on the IRLR?

the picture is just *lol* sry like my little brother drawed it
