350W is not enough to powering 8800GT, get a minimum 500W...

but many people have nvidia 250gtx with cooler master 350w
and my freind have same graphic card with PSU cooler master 350

i think the source of the problem is graphic card 8800

and this card id not so strong to need that volume of power

i will be crazy

in this moment i playing modern warfare 2 without any crash with hight setting and same talk withe hawx

but when i playing resident evill 5 after 10 minute or more the game close directly

if the power is not enough the cod 6 should be not run

i think found the source of trouble

i plug my card into my second pc acer desktop and work fine
all games work perfect

i plug the memory of my first pc to second pc and every thing okey
same action with hardisk

so
i think gygabyte motherboard is th problem

i find in bios two option

PCIE frequence
