I also have Bryce 7 on my Windows 7 64-bit, also with 8gb of ram. (I can guarantee the rest of my hardware is much older than what you have)

I can only guess but here are some VERY random thoughts;

Try uninstalling Bryce and re-installing it. Install latest video card drivers, always use video card drivers from the manufactuorer NEVER the ones from Microsoft.

Try and not do any other work on your computer when rendering. (yeah, I know, that sucks) This should ALWAYS include disabling automatic windows updates!! I disable EVERYTHING that is "Auto" in the OS and in EVERY single program I have installed.

These are all just basic guesses at solving your problem. They may or may not help at all. Best of luck in your trouble-shooting!
