Did your computer restart all by itself? Don’t worry this has happened to most people at some point and typically is nothing to worry about. There are a couple of common things that could be the culprit.
- One issue could be Dust. If a computer isn't properly cleaned on a regular basis, then the components, fans, etc. can become coated in dust keeping the computer from cooling properly. Most modern computers are set to shut down if they start to overheat. The solution would be to open the computer and, with a can of compressed air, gently blow the dust off of the components, fans, etc.
- The culprit we always recommend investigating are Windows Updates. Whether it’s to save time or because the computer came preset this way, Windows may be updating automatically. When these updates are run the computer must restart to apply the changes. If this is the case, then go into the Control Panel > Systems and Security > Windows Update > Change Settings. Here the preferences can be set for if and when to update, to manually or automatically update, and even schedule the update. If the issues persist after making these changes, then it might be time to call a professional.
- Another issue could be that the Computer has a Virus. If this is the suspected issue, then run a virus program such as Kaspersky or Norton and the problem should be solved.
