It sounds like you have a hardware problem not a software problem. NVidia says you should have at least a 300W power supply in your computer for the GeForce GT 430. If you have that, my guess is that your video card is overheading -- it could be that the fan on the video card isn't working, or perhaps the fan in the computer case isn't working, or that the inlets for the fans on the computer case are clogged. And there's always the possibility that the computer's power supply is defective.

Good luck,

Greg

P.S. ATI/AMD Radeon video cards are as good as NVidia GeForce video cards and ATI's current video drivers are finally as good as the NVidia video drivers, so depending on the particular model, you might be much better off with the ATI Radeon. See the graphics chart at the end of one of the "Best Graphics Cards For The Money" articles at www.tomshardware.com for approximate relative rankings.

Dear Chimera development team,

I have a little problem when I use Chimera with my new Video card Nvidia geforce GT 430. Chimera runs well the firsts 2 minutes but, then, it gets stucked and I can't move whatever I had open in these moment (even if I had a little model of less than 50 atoms!). I've been updated the drivers of the video card twice and also I re-installed the operating System but Chimera remains getting stucked.

Before change the Video Card (first I had a ATI Radeon (I don't remember the model) of 1GB) Chimera runs perfectly.

Anyone has any idea of how can I fix it without change the video card? (the best solution is using back the ATI video card... but I want to use NVidia in my computer)

I'm running Chimera over Linux (Opensuse 11.0 32 bits and Opensuse 12.1 64 bits) in a Intel Dual core CPU E8400 @ 3.00 GHz with 2 GB of RAM.

Thank you in advance.
