Well, I'm sorry to say that my mother's Imac has a serious problem. I'm 99% certain it's the PSU, but it could be the "logic board" or whatever the heck Apple calls it's motherboards. I'm not spending $160 for a new PSU when that might not even be the problem. Oh well. It was only a 20" anyway. I need to get her a 24." Her vision's not that good. Unfortunately, I don't have $1,000 to buy her another one right now. <_< I guess I'll post her existing one on Craigslist for $250 or something and maybe someone would be willing to take a chance on it. It's easily worth $600 so maybe they would.......
