I have a system that I believe it is quite stable as I don't really have panic anymore but it freezes when I run video encoding software also under Windows.

I changed power supply and memory (did have 4X2GB, but now 2X4GB and 2X2GB) and still does that. One of my buddy tells me it could be graphic card.

I never thought graphic card has to do anything with video encoding but is it?

I have a refurbished HD5670 and wonder if that could be the case.

What do you think?

Thanks in advance.
