Just bought a ATi 9600XT today and installed it but now I am having issues running it for some reason.

I boot up and am able to run windows for a short period then the card shuts down on me and won't run. I have a 300w power supply that is in excellent working order and am running 2 hard drives 2 DVD Roms and a floppy off it.

Am I drawing too much power and it is forcing the vid card to shut down? or am I missing something here?

I installed as usual and set it to 1280x1024 resolution and figured I would drop a level but it won't stay booted long enough to let me do it.

The fan is working fine and I have another floor fan blowing on the case just in case that was the issue but it doesn't seem to be doing anything to help

Help!!!!
