In this lesson we cover a few troubleshooting tips you can try yourself before calling tech support. If the challenge you are having is just a software issue, like an application isn’t working quite right, there are steps you can take to try and fix it. Dan walks you through these steps – from rebooting to repairing your disk. If you’re having hardware issues, you’ll probably need to take your computer into a repair store. Remember before you attempt any repairs, always make sure you have a back-up of your data on an external hard drive.
