Warning the follow is going over thought process of trouble shooting a computer:
A problem has occurred with your computer time for jumping into troubleshooting right? Wait a moment there.
Have you ever stopped to actual think your way through the troubleshoot?
What if all it took to trouble shoot was basic If this, then? Because this a critical thinking way of trouble shooting.
If this computer has a problem, then can you replicate the problem?
If you can replicate the problem, then do others also have the same problem?
If others have the same problem, then does one of them have a solution?
Wait what is the point of all this? That in itself. The If Then is the core basic of critical thinking. With If Then you can build off and create more complex stuff in relation to troubleshooting in computers.
Next let’s go to If And Then for trouble shooting. If And Then is more advanced than If Then. The and creates an addition for the If that must be met for the Then to apply. This creates a rule or law so to speak. What happens if the and isn’t met? Then the then doesn’t apply or happen.
If wifi isn’t working and the os is Dibian, then you’ll need the Wi-Fi Drivers installed.
The problem is the wi fi isn’t working and the condition is the operating system is Debian. The then is the solution to the trouble shoot: install the Wi-Fi Drivers.
Laws for Troubleshooting
First Let us define what a law is in relation to Troubleshooting. This isn’t law in the legal sense but more so along the lines of a law like law for scientific theory. In common term this means it is an absolute and always true
Always Get Drivers from the main website of the maker - ie GPU Drivers for AMD Cards get them from the AMD site.
Maintenance is the best prevention from having to trouble shoot often.
Linux Distros have documentation that will answer most basic troubleshooting issues with said Linux Distros.
Check to See What RAM has actually been tested to work with the motherboard you have before you get the RAM
Have at least 1 back storage solution. 2 back up solutions are better though.
Give yourself enough time to troubleshoot the problem.
