I’ve been using Geek Uninstaller to delete programs ever since I read your post explaining how Windows leaves bits and pieces of a program behind when it deletes it.

Question from Elaine: I came home from work yesterday evening and the power company was replacing a light pole in the neighbor’s yard that had been broken off by a wrecked car.

When I press the power button nothing happens. No noise of any kind, and no lights – nothing.

I know the outlet is working because I plugged a lamp into the same power strip and it’s working fine.

Do you think the broken light pole fried my computer somehow? And if it did, can it be fixed? [Read more…]

Question from Brenda: I’m having my house renovated and I’m in the process of ordering all new appliances.

The man at Home Depot said I’d have to pay extra for a special cord for both the electric range and the clothes dryer because they run on 240 volts instead of 120.

When I asked him why he said he didn’t know, but that’s just the way it is.

My question is, why do ranges and dryers use 240 volts when all the other appliances use 120 volts? [Read more…]
