My Sony VAIO Laptop (PCG-C1VN) starts ok but then only boots in Save mode.
It is about 6 years old, has XP-Pro on it. It's had its growing pains, but was working fine for about a year.
Previous problems were usually the result of being handled roughly going back and forth to school each day, it would not be able to find the OS, then the Tech re-seated everything and it lived on for another day.
Now, without warning and it was in the house for a year just being used for internet browsing, it can't boot to normal mode.
It looks like it's starting up ok with Windows XP, then a blue screen of death flashes, then a black screen that says "Windows did not start successfully . . . Choose Safe mode, safe mode with networking, or safe mode with command prompt.
It still boots in safe mode, so something's still working ok.
How can I troubleshoot the boot problem?
