Try turning it off and on again
Yes, it is as simple but is so very often overlooked. But there are a few other things to keep in mind:
- If we are talking about your computer then shut the computer down first (if it can). The best thing you can do is turn if off at the mains. With a laptop, disconnect the power and also take out the battery.
- Leave it powered off for at least 30 seconds,
- Then turn it back on.
One final tip is to remember to restart your computer at least every 24 hours.
