Hi Well my computer is clean of dust and the fans are turning fine, but it is still switching itself off at times. No all the time. I was wondering if this room is too warm because it doesn't switch itself off if I have the patio door open and there is air coming in. Could this be the problem? Also the computer is on a different computer des which has a piece of wood going across the back which I wondered maybe restricting the air flow. Any suggestions would be appreciated.
