Marvel Man thank you for your reply, you asked which windows program I use, at present it is Windows 10 pro but the problem started before that when I was still on Windows7.

What actually happens is, I can load what ever I like in terms of Video and or Photos as well as Audio I can edit, however once I have edited and want to save the Movie, the program starts to save the movie and has reached any percentage  above 50 my computer  kicks out. I do have a laptop and when I do the same on the laptop there is no problem the laptop is also on windows 10 home. Hope the above is sufficient info . thanks. Regards
