Right, I've had a serious issue with my desktop PC for roughly a couple months now. Basically what happens is it completely crashes, shuts down and switches off to a black screen whenever I render/export ANYTHING that takes over roughly 10 minutes to render/export. This goes for rendering with 3D studio max, Vegas, and rendering to burn with DVD architect. So I'm guessing it's a hardware issue. As you can imagine it's really hampering my productions. My first thought is the graphics card overheating or something, but my PC is in standard room temperture, and checking the card after a crash, it doesn't seem hot. However, the power supply is a bit hot. Could it be this? Would just really like to know the likely cause so the part can be replaced.... PC spec off the top of my head: Window XP home AMD dual core 2GB ram GeForce 8600 GT 7200rpm SATA Cheers.
