Few days ago i buy nvidia geforce GTX 295. I put it in my P5N-E SLI motherboard and i was seeing that cable is not connected. Green light is on, fan is spinning, NO BLUE LIGHT. I can hear windows welcome sound. My psu is 800w full atx. I am using D-SUB to DVI cable adapter. Also tried HDMI cable. Tried to pit in another slot. Still no video. Any help?
Try another monitor. If the card were dead (I know I've got a 295GTX to RMA) the computer will give you a beep code and won't get to windows. Either the monitor is not working or the output on the card is broken.
