My computer is throwing random errors or issues. What is the first thing I should try.

Sometimes the best remedy is a quick reboot. Unless you have a very clear indication of an issue e.g. a message from your antivirus, malware software or from your operating system of an exact error, you will always want to try a quick reboot first. That very often will rectify simple software issues. If your computer has a very specific error message, your best bet is to use the Snipping Tool in Windows to take a screenshot of the issue to submit to support.
