Ok guys a few hours ago i was running 3dmark06 i was on the cpu testing part, decided to go out and smoke when i got back the computer was turned off and when i tried to turn the power nothing... pulled everything part including cpu, still the same it wont power up. i narrowed three of the problems either i have a fried cpu, or mobo, or loose contact from the cpu socket, i can see my ethernet lite up everytime i turn on the power. i tred my old 3000+ venice and same results.. anymore ideas i can try so i can narrow down and trouble shoot this problem? and by the way which of the connectors u have to ground/ in order to turn on the psu? and oh yeah prior to running 3dmark06 my opteron was running 5 hours occt so its safe to say its was stable.
