I don't consider myself a computer novice, but I have encountered a continuous problem that I just can't seem to correct. Since November, my son and I have fried 5 motherboards...in two different computers...and opposite ends of the house. I know you'll ask me what kind of Mobos we're using, but that doesn't seem to matter. One was a Soltek, two were Epox, one was DFI and the most recent was Biostar. I could go into the models, but, again, I don't think it matters. Our boxes are fairly new. We each built our own computers from parts purchased through Newegg.com. Mine was built exactly a year ago, my son's a few months before that. New cases, new components, etc. At opposite ends of the house, we are on different circuits. The only similarity we have between our computers is the cable Internet line. We're both hooked in to the same router. Any suggestions? I'm getting more than a little frustrated.
