Hi everyone. IN december my apartment caught fire and I had a custom build pc that i made. I had 3 gtx 260's core 216 edition. How do I go about testing them to see if they work correctly. I tried to turn on the computer with an old zalman 850 watt hooked up to each card by itself and comp wouldnt start. psu fan spins and shuts right down. Is that the only way to see if they work correctly is by putting them in mobo and hooking up to psu?
