Well you did not give enough information for anyone to help you out.
It is your system, just to start it could be your java is not current, players are not current, your security settengs are set wrong, Privacy setting are set wrong, Folder options are set wrong, etc...
Or it could be as simple as your system just needs to have the latest update's. For windows, from start, chose program's, then widows update.
Also when is the last time you cleaned up your disk?
But on the brighter side of life and the wonderfull world of computers help is around and your problem is not that bad.
