Laptop has been working fine this morning, got in from work and ran disk clean up. When it finished shut it down and went to bed. Since I switched it back on, it wasn't finding anything plugged into usb. Specifically an external HDD and my phone. Did a System restore and now all its got on screen is my desktop picture, but enlarged and thats it. Can get task manager up and its only showing 20 processes instead of the normal 40-42. Hitting the windows key does the sum total of nowt too. Any ideas?
