First off try cleaning the computer, open it and clear all the dust. After that take the RAM out and put it back. Swap if you have multiple RAM's. If this doesnt help try using the Windows Repair Utility with the windows disk you have. Make backups first if you need to Ultimately format the drive. You can also note the error code form BSOD and research online based on the code and you can figure out whats wrong with the Box.
