Recently my Sony Vaio laptop has been spontaneously shutting down. I recently had a trojan virus but that was removed and I continue regular checks. I also added a 4gb stick of ram, exactly the same as the existing 2 months ago, however that is installed correctly.
I was concerned that it was overheating so I have tried a resource monitor and the heat never tends to reach higher than 65°c. Following that I wondered if there was a dust build up so tried to open it up and have a clean, however a couple of the screws are stuck. I'm not sure its the power supply or battery either, as I've tried running the computer without one or the other and with both to have the same issue.
Anyone got some advice or any bright ideas?
