I'm currently trying to run Lumion 2 on my windows XP workstation. Have just installed a GTX 590 GPU. The GTX's 2 power inputs are hooked up to one power source (disconnected CD drive) on my PC.
Graphics card seems to be working fine in general, but when I loap up Lumion, the whole PC shuts down after a minute or so. And when I say 'shuts down' I mean instant black screen, dead PC. The PC comes back to life ok when I restart.
I'm wondering if this is a power source issue, an over heating issue, or something else? Regarding overheating - it seems strange that it would over heat so quickly - seconds after starting up Lumion, so I'm wondering if it's the power supply?
Any help or suggestions much appreciated.
