Did you upgrade the MoBo and CPU? And do other games still work? Sounds a lot like me trying to figure out what was wrong with my new computer when I tried to use a PCI-E 2.0 graphics card on a PCI-E 1.1 MoBo.

A word of advice, many 9600 GT cards have loud, noisy fans and cooling issues, especially the model with the small fan. If you can afford it, I would highly recommend the sapphire 4850 512mb dual slot card. http://www.newegg.com/Product/Product.aspx?Item=N82E16814102770 It's worth the difference in price in my opinion. Ultra high settings on most games, except crysis, which ofcourse is also dependant on the rest of the system.
As sins uses only a single cpu-core after texture loading, it wouldn't surprise me one bit if it only supported a single graphics card as well. My apologies for the lack of an answer.
KnackeredOldGit please do, their solution or the one you might find out yourself might be of use to others. Did you already try running the game in windowed mode? It has helped a few people in the past.
Cooling helps. I don't know how you rigged your computer but making it run cool (and quietly preferably) makes a lot of difference. I myself use a dual core 3 ghz processor and 4 gig's of DDR2 ram with an ati 4850 and the game runs fine, even on huge maps with lots of (cpu)players, with the sole exception of large fleet battles, which zoomed in which provides me with some slowdown in-game. For example, a friend of mine who has a very simular or even better setup uses a stock cpu-coole
Try registring the game on the link in your post and download impulse (https://www.sinsofasolarempire.com/downloads.aspx). Impulse should take care of the updating by itself.

Have you tried getting your drivers from laptopvideo2go.com as suggested in the technical faq? Otherwise try updating your sound drivers as well. Many games running on Vista act odd without recent sound drivers. [quote] I have an NVIDIA card and my game or video driver keeps crashing! <span style="color: #000000;"
Make sure your graphics drivers are compliant with your video card. In the case of an ATI card sometimes installing select versions of the catalyst driver in combination with a certain card causes these problems.
See if you have stereo mixing enabled. go to: Control panel > sound (classic view) > tab "recording" > right click and see if there's a "v" in front of "show disabled devices", if not click it. Then enable stereo mixing. Hey Carl, I just left this same message in your thread in another forum I believe. [e digicons]:waaaa:[/e]
Sometimes the audio in games on Vista gets somewhat mixed-up depending on what settings you use. Try going to your control panel, make it the classic view, select sound, then the tab recording. right-click and see if there's a "v" nect to disabled devices. If not so click it. Then enable stereo mixing. I hope it helps.
