Hi
As per your minimal description of the problem, I could tell you that a A blue screen of death is the worst type of error a computer can encounter with. It is caused due to memory issues mainly and also due to certain operating system files getting corrupted. From my one year of experience in this field, i can tell you that such an error cannot be rectified remotely.
But If u can provide me further details regarding how it started, then i can help u in troubleshooting the same by yourself. Feel free to reach me for further assistance.
Thank You.
