OP's who don't realize that help steps are interactive and need more than "Didn't work" posted back after a dozen steps are given.
If I ask them which didn't work, it always seems they only tried one or two and maybe didn't even do it right. I'll try to motivate them to work through the steps, but it seems some are just plan lazy and/or careless.
Do they realize this is hundreds of dollars worth of troubleshooting and multiple tutors' lessons at the same time? These forums may provide tens of thousands of dollars worth of free help in a single day - or more!
This past weekend I was hired by a Delta agent who is on leave to care for her husband recovering from brain surgery, to rescue two 10-year old XP computers which were crippled by hundreds of trojan viruses to where Factory Recovery couldn't run. Via TeamViewer I tried disinfecting, rescued files from both, reinstalled XP and optimized them better than a new machine, but couldn't bring myself to charge the disabled husband more than $100 - in part because I considered it practice on XP which is fading in my own memory. If the wife hadn't been fully interactive via phone I would have had to make a housecall which is never cheap when it's cross-country.
Quick story: She wanted her husband to practice some so she had him set up the second XP during install. He forgot the password he made while I walked away to make coffee, so we had to do it over.
