I decided to take time off a couple of weeks ago to put together a Pentium 4 computer for my kids, they've been learning about computers in school for years now and for the most part, we had been sharing the computer in our bedroom.
So I went online and searched google for what was the best step by step process of putting a computer together.
I read and re-read the instructions, before finally deciding to go to the surplus shop and buy the parts needed to put together one.
After about 3 hours putting it all together, I plugged the computer in the AVR and turned it on...at least I pushed the power button, but nothing happened.
After 3 hours of tinkering, taking the computer apart and putting it together again, I decided that the problem was most probably the old motherboard I was using.
I decided to go back to the surplus shop to buy another motherboard, in order to make sure that it worked, I asked the store's technicians to power it up for me, which they gladly did to make sure that the board was in good working condition.
15 minutes pass and they effortlessly demo the unit to show that its working. It's dinner time when I get home and so I hastily eat dinner, so that I can get back to work.
After another 3 hours of putting the computer together, I try again and again to power it up and to my frustration...nothing happens.
By now I am dead tired, so I decide to call it a night.
I don't know about you, but I don't like the feeling of not having been able to finish what I started and after twisting and turning in bed all night, I decided to get back at it early the next day.
It was during this time that I decided to check where the AVR was plugged and to my horror, it was plugged into the 110V socket.
No wonder the computer wouldn't power up, the AVR is 220V!
Not surprisingly, the computer started without a glitch when I plugged the AVR into the 220V socket!
Now that's what I call root cause analysis!
