Pat with regards your laptop download ccleaner from their website below and run it on your laptop it will clean all the bits of old programmes and software left on your system which slows it down and it may run better. Download the "Free" version. Or take the free trial of one of the others and do not take up their offer to buy after the trial period the next update will revert it to the free version. I would use the pro version to clear your laptop on it's first run. When you use it do not clean first of all run the registry clean the second one down of the menu then click scan for issues and when that's finished fix all. Then run cleaner with the little brush icon. It's very easy and good luck. I have used it for years and it has never deleted anything it shouldn't have.  :D
