APPCRASH Error

I am running vista on my computer and I was using it on a car charger that convert from the battery of the car to 110 volt and it was giving me a message of unrecognized power but it kept the computer running. Yesterday when I unplugged it my computer went out as if I had turned it off, so I plugged it back in and turned it on and the computer started. I used it for 1 hour then I unplugged it again and it went dead right away. I plugged it back in and tried to start it and didn't start. I tried different chargers and none of them worked. I even took the battery out and it stayed dead. I pulled the hard drive out and put it on a differenet compter and it gave me a message that Quickset stopped working. I opened the problem explanation and it said:
