This laptop gives a blue screen while starting
The error seems to revolve around srtspl64.sys
Fortunately, the PC starts fine in safe mode.
A quick search shows that the error is most likely due to norton / symantec security problems.
So I disable all symantec and norton services and automatic startup routines, and then manage to start windows normally.
After that, its easy: uninstall norton, and install Microsoft security essentials
