Final Analysis

Based on your input:

The computer turns on and boots into Windows but crashes to a blue screen.

Conclusion:

Most Blue Screen problems indicate that Windows software has become highly unstable or corrupt.  This is usually not caused by a virus.  Customers often see these after installing a new software/hardware OR after an undesirable update.  If this happens once it may be nothing, if it's a regular issue we can reinstall your Windows Operating System.
