Hello, I hope someone can help me out This is my story PNY nVidia 6800 GT (No OC, drivers updated) One day I tried a cheap 450 W PSU and made a stress test in Counter Strike Source but suddenly puf!! the PSU went to another life. Inmediately I changed it back to my old 350W and everything was OK. Hours later my monitor went black, I rebooted and hours later the same story. I moved the vcard to 3 different PCs to see if it was a bad configuration in my sistem or a HardWare issue that causes this, but I had the same problem on those different PCs. I dont have video signal on the VGA neither on DVI. The PC boots, I can hear the start up windows sound. The fan is on, but I NEVER get video signal. Now I have to use my old video card... :dead: Is there anything to do before I ask for my RMA?
