My Dell Inspiron 1525 has suddenly decided not to turn on. I get up to a Windows Vista screen where it says "Configuring updates stage 3/3" and then it restarts itself again and again. I can't get it to do anything else. Before it wasn't even getting that far and it was restarting itself and giving me the option to launch startup repair which I did. I tried to restore the system but I was told that there were no system restore points. I turned it off and on again and it then started to take me up to the configuring updates page but no further than that and I no longer get the launch startup repair option. I have also been having a problem with the battery where every time I turn it on it says "ac power adapter wattage and type cannot be determined" and then won't charge so I can only run it when plugged in but at the moment I would just like to get it to turn on!
Any help would be appreciated,
