Over the last month or so my Laptop seems to get very hot and then it will shut itself down automatically. I have a Toshiba satellite, about two years old. Not sure of the model number. The problem seems to be happening more than ever now. Also when doing a full AVG antivirus scan it never completes and will overheat and turn itself off. Is it worth buying pressurised air and blowing into the vents or is there another solution. Maybe to many progammes are running on startup also.. any help appreciated.
