Hello everyone, First time poster, having an issue I couldn't solve through your search function or google. I have a XFX GeForce 9600 GSO 768mb PCI-E card. I have had it for 3 months now, running great on my machine. I have an Ultra 500 watt PSU. Today while browsing the web my computer shut down as if I pulled the cord out of the wall, I was unsure of the problems and after 4 hours of physical inspection and trying everything possible I have come to the conclusion that the video card mentioned is the problem. System will not even power on if the card is connected to the PSU through the 6 pin connector. I've replaced the PSU, replaced my Power Button (thought these were the problems first) and nothing is responding with my graphics card plugged into the PSU. The computer runs fine with Onboard video on and I don't have another video card to test the slot. Kinda on a low low budget atm too. Things only 3 months old and was running like a champ, so I am confused. Any help on this would be great! Thank you, Sulamar PS: I have Windows XP Professions AM2 2.61 Dual Core / 2 GB memory (checked and they are running fine) Any help would be greatly appreciated. Reiterating the PSU has been checked and does work.
