it could be larger file size, not really sure. I'm almost totally computer illiterate. All I know is it worked fine a month ago but now it is constantly stopping and stalling throughout the movie. Usually the screen will stop on a frame but the sound will keep going, then if I pause it it will "catch up" play for another min or two then stop again. Very annoying while tring to watch movie
Sounds like you've got a lot running on the laptop. I'd exit any applications in the system tray, and use CCleaner (google it) to clean out windows and the registry.
Also try a defrag with Auslogics Disk Defrag or Defraggler. (all are free)
I did that yesterday, (after skimming through some posts here, thanks guys) to no avail. Removed a bunch of programs I don't use anymore, there are a bunch of HP stuff that came on the computer that I don't use, can I remove these as well.
