Yes fault was found it was motherboard.
I bought today Asus M2N-SLI Deluxe board and played crysis to end (and pulled my hair in my head cursing that last boss).
Here are some faults that are caused by wrong capacitor
Unable to use udma66 dvd-writer (pc shutsdown when burning dvd&cd). (udma33 works well no hiccups).
Unable to install x-fi soundcard in win xp (middle of driver installation pc shutsdown and doesn't start until you go safe mode remove drivers).
(however in vista drivers install fine and card works).
Crysis pc shutsdown in beginning of paradise lost level (no matter is pc run hours or just minutes it will shutdown in exact same spot).
And all this is fixed by new motherboard (same chipset nforce 570 sli)
Im happy camper now
