Electronic Stone age

On Friday night, I broke one of my main computer rules: I turned off the system. It seems like anytime a computer breaks, it happens when you turn it off. That is exactly what happened. The computer that I built on January 10 decided to go dead after I turned it off on July 27.
Dead. The power button doesn't do anything. The power light is on, but that is the only indication of life. The power supply checks out fine, so a 6 month old EVGA motherboard is dead, the second to die like that this year. I don't think lightning is the cause, as I run the system over a WiFi internet connection, and it is powered with a UPS, which is working fine.
I ordered a new MoBo(an AsRock this time), and it will be here by Thursday. In the meantime, I am tryping this on an older system.
This computer is a Pentium 4 with 512 MB of RAM.
Slow is not the word. At least it is better than the old days, when I had a 4800 baud modem. At any rate, I am checking email on an iPhone, and since the system I have is so slow, no internet and no blogging until my system is back up. That should be Thursday night or Friday.
