Okay here is the problem, bought a new graphics card(ATI radeon 2600 pro 512mb) to replace the 128mb ATI that was in the Dell xps 400 desktop. I followed the installation guide and once I got everything plugged back in the computer starts up on its own and runs for about a minute and then cuts off, and keeps doing this until you cut the power. I also upgraded the power supply from a 350 watt to a 650 watt, hoping that a boost in power would be the solution, but it wasn't. Can anyone help?
