our p/b gaming comp keeps randomly turning itself off, it happens when we are just surfing the web, it has no warning to say its going to do it, it restarts fine and then shuts down again, it can be turned on again immediately, any clues/ideas/suggestions would be greatly appreciated and of course save us a small fortune at pcworld! thankyou

take the side casing off and clean the dust out of heatsink on the processor etc.Then retry.I would also disconnect all connections and hardware to main motherboard as well to eliminate poor connections especially on ram chips
