I am using windows 7 operating system with core i7-920 processor, 6GB RAM, dual GTX 260 video cards, and Win7 64bit. As I have sufficient RAM and updated drivers and also have a cooler-master Pentium 4. I desired to start windows live movie maker on this system but it fails to start on this configuration I think so. I am trying windows live movie maker first time and using windows 7 from last on year. Any suggestion to get the proper solution. Please help me.
