Understanding Safe Mode no comments

Worst. Feeling. In. The. World. You're happily typing away without a care in the world when Wah-Bam! Screen freezes. Or it goes completely dark. Either way you reboot your system and your computer (with cunning subtlety) suggests you start your computer in Safe Mode.
So what exactly is safe-mode and why should one use it? Safe mode is a diagnostic setting on your operating system. Safe Mode is supposed to help you find and fix any errors that might be running on your computer (or for catching viruses, if that is the case). Safe Mode shuts down all the superfluous programs on your computer. So if you've just had a mini-overload and plan to go right back to what you were working on, you probably don't need to reset your computer to Safe Mode.
Here are some Safe Mode tips if you use Windows as your OS (Operating System).
1. To get into Safe Mode at any time press F8 during boot-up.
2. If you want to use Safe Mode to trouble shoot try running the Recovery Console which is a separate diagnostic system from the main operating system. Note: the Recovery Console is a text-based prompt, so find a walk-through before trying this by yourself if you're not sure what to do.
3. If your computer won't boot outside of Safe Mode or continues to have trouble running, call an expert. The worst thing in the world is trying to fix something when you aren't sure what you're doing. It can cause more harm than good and usually makes things more expensive.
