Computer Troubleshooting Basics 101

CHECK FIRST
Before asking for help from someone or bringing your computer to the PC shop, why not check it out yourself?

P: My computer does not turn on.
A: Have you checked the plug of your tower? It should to straight to your outlet. Some got AVRs or Voltage Regulator, do you have one? Check if its powered ON.

P: Plug in the outlet, AVR is powered ON, still not working.
A: Did you turn the tower ON? A mark on the button that looks similar to this It depends on where your power button is situated, if its not at the front, check the sides, back is not possible, or maybe...hmmm, i haven't encountered it yet.

P: I tried pressing the power button of the tower but it does not light up.
A: Check the connections at the back of your tower, you might miss one out. If everything is in and still not working, then the PSU might be a problem. It's actually a DIY repair but you can also bring it to the shop if your not confident enough.

P: The tower is ON but i don't see anything in my monitor.
A: Check if your monitor is powered ON. Look for the button.
