Hello! I got myself a video card <ASUS GeForce 6600, (256 MB) AGP>. I pluged it in. When I turn the PC on, the monitor is in standby (orange led), all fans start, I can't hear any beeps and after 5 seconds it suddenly turns off. My system is: ASUS P4V8X-X (motherboard) Intel pentium 4 @ 2.4 GHZ 3 x 512 DDR DVD-RW 160GB HDD ASUS GeForce 6600 Floppy 2 fans (one on the CPU and a smaller one) My first guess was that my 450W (no name) PSU couldn't handle it. But then I tried the videocard on another PC with a 350W PSU and it worked like a charm. When I put the card and the PSU (the 350W one) on my system, it turns off again. What I tried so far: - update bios - reset bios (+load defaults) - unpluged everything except videocard and HDD. My system works perfectly without the videocard. When I put the videocard in it turns off. Could anyone help me?
