This actually happened to me
Question: What would you say to someone who said?:
"In Windows, usually when I'm checking my email, my PC restarts itself"
"Windows won't open video files any more - it just restarts itself"
"My PC gets to the first boot up screen and stops for 20-30 seconds and reboots"
"Sometimes when I press the button at the front it just beeps and I have to turn it off via the socket on the wall but if I leave it a while I can start it normally"
"Sometimes my PC makes a noise like a car engine repeatedly turning over for no reason"
"Do you think I should go to PC World?"
Answer: Don't go to PC World - Currys do better deals on vacuum cleaners
Never seen so much fluff in one place before - indescribable smell too - yuk
