Please help. I have an eMachines ET1331G-03w. It has a cheap integrated graphics card and I purchased a new Galaxy GeForce GT 430 graphics card along with a Thermaltake TR2 600w PSU yesterday. I installed both and powered the pc up. The fans fired up in the PSU, the Processor, and the new graphics card. I had my monitor that I had been using with VGA hooked up with an HDMI cable. Now comes the problem. I am not getting any picture whatsoever on my monitor. It says no signal and it wont show any picture, even at the start up. I tried two different HDMI cables, I tried a VGA, and I tried a DVI. None of these made anything appear on the monitor. I turned the system off, took out the new graphics card, removed the new power supply and put the original one back in, and tried to fire it up. Now I have now picture with my original computer plugged into the original VGA slot. I have no idea what to do and I am only a beginner when it comes to installing things into a PC. I have asked around and no one had any idea how to solve this problem. I don't want to have to buy a new computer just because I tried to upgrade this one. That would suck. If anyone could help it would be greatly appreciated.
