Basic Troubleshooting Tips for your PC and Internet Connection - Part 2

Previously, we've learned about the difference between slow pc performance and slow internet connection. This time around, I've prepared some tips for troubleshooting no internet connection and no boot.

No Internet Connection

Please bear in mind that the following basic troubleshooting steps are only applicable for DSL connection.

For wired connection (via LAN cable):

There are only two important things that you need to check to determine if you have a connection: a DSL signal and an IP address – keep this in mind, as I will be giving you diagnosing and troubleshooting steps based on these two points of failure.

a. DSL signal. Check your physical setup
- Are all cables properly connected (Fastest way to check is if the DSL modem’s activity lights are all on – power, ethernet, and DSL or activity)?
- If at least one of them is not lit, check all cables; reconnect or swap with good cables if necessary.

b. IP address
- Once verified that DSL signal is not present, test your connection by opening your web browser and visit a particular site.
- If your browser is not able to open any website, you will need to check if your IP address is correct.
- Go to Start > Run > type cmd > click Ok (It should bring up a black screen – A DOS command window).
- On the blinking cursor on the DOS screen, type ipconfig /all then press Enter.
- Check for the IP Address. If the IP address indicated is 0.0.0.0 or 169.254.x.x then do the following:
1) On the blinking cursor type ipconfig/release then hit Enter.
2) This time, type ipconfig/renew then hit Enter. It should now give you a new IP address.
3) Type exit then hit Enter. This should close the command prompt window
4) Open Internet Explorer then try going to a website and see if it works.

PC not working
I know I promised that the troubleshooting steps that I’ll be posting are basic, so I won’t be giving any instructions on opening your system unit, and check internal components. There are three things that I want you to remember though and these are the stages that you computer will have to pass before finally displaying your desktop screen on your monitor.
1. Power
2. POST (Power on Self Test)
3. Boot

Power
In this stage, the first thing that you will have to check of course is if your PC is receiving electricity. I know it sounds funny, but before we conclude that the pc is ready to be thrown out of the window, it would help if we check first some basic things:
a. Is the power button on? It won’t do any harm if your try to press in again.
b. Is the pc connected to a good wall outlet? If you’re in doubt, try a different wall outlet.
c. Is the monitor cable properly connected to the back of the pc?

POST
Once you’ve verified that your computer is receiving power, the next thing that you will have to check is if it does the power on self-test. Here are some indications of a successful post:
a. If the Numlock and Scroll lock lights on your keyboard suddenly turn on and turn off (blink, that is)
b. If it does a quick memory count
c. If you see the Windows splash screen (obviously, because this part is already the boot stage)

Boot
Boot simply means that this stage is when your operating system (Windows) loads. If Windows does not load completely, then this might by an indication that it needs to be reinstalled. That’s why I always suggest to BACKUP your files! You’ll never know when this would happen.
