Thanks a million ! will go over your steps and check where they differed from the source I got from "Google" (just learnt that one from my daughter). At the end the result was 00:04:24.36, but don't know if that is good or bad.
Then tried an app "PC Benchmark", but again I'm unable to decipher the results as there is no comparison (I think) to what would a standard. Have attached (hopefully) this screen shot.
Thanks immensely for all your effort. It's been most appreciated. Didn't realize these forums could be so helpful!
