Firstly my laptop (Dell Inspiron 1521, Vista) is refusing to run iTunes and Skype.
What happens is the screen freezes, the hard drive LED stops, the mouse pointer stops and Ctrl, Alt, Del won't work. Skype starts and runs for a bit before this happens but iTunes will not even appear. The only solution that works at the time is power off.
I have tried taking it back to a restore point but that didn't work.
I have attempted to use Dell's PCRestore.exe in my D (Recovery) partition but that is showing a blank error message.
