the dreaded Blue-Screen of death.
Usually caused by:- Ram Failure ( memory Modules )
CPU Failure ( Processor Failure )
Hard-Disk faulty, not spinning et,c.

Missing/deleted/corrupted operating System files.

Possible Solutions:- remove cmos battery, from Motherboard for 10 seconds and replace. ( eliminates cmos/bios errors )
remove 1 stick of Memory ( Ram ) and test individually ( eliminates 1 or More Faulty sticks Of memory Or Slots )
remove, CPU Fan/heatsink, remove CPU and re-seat, re-grease with Artic-Silver or similar ( thermal-Compound ) replace heatsink/Fan. test.
