BleepingComputer.com: Blue Screen after Windows update

I've had my Dell Inspiron notebook since about Feb. of this year. Everytime my window vista updates itself my computer crashes and has to go to a restore point. Is there anyway I can correct this without having to delete everything and starting over?

Step by step what happens:

1) Windows will update
2) I will restart the computer
3) The windows will begin the booting process
4) The computer then switches to a dark blue screen, the crash dumping screen


Any help here would be greatly appreciated.
