Hello, I'm using DVD Architect 1.0d. I had a project done and when I open it, Prepare, or Prepare & Burn, in about 15% overall or 5% Video rendering my computer automatically reboots, completely restarts. -- I am using a Pentium 4 2.8GHz 512DDR RAM 333.
Is your processor overheating? Rendering is a CPU intensive task, and this will usually cause the CPU temp to rise. If you're right on the edge, getting too hot can cause this type of behavior. Try opening up your case and making sure your fan is working and the fan/heatsink are clear of dust (I use one of those compressed air cans to clean mine periodically.
