My Laptop on startup displays blank screen...not even the boot logo is displayed?

[Elnino_1]

I have a lenovo z51-70 series laptop and it crashed suddenly one day (System_service_error) and after that every time I restart I only get a blank screen and not even the lenovo boot logo....is it because of GPU driver problem ?

This error is caused by a system file not a driver.
There are 2 things you can try:

1) Click the Start button then select All Programs, Accessories, System Tools, and then click System Restore.
2) In the new window, select "Restore my computer to an earlier time" option and then click Next.
3) Select the most recent system restore point from the "On this list, click a restore point" list, and then click Next.
4) Click Next on the confirmation window.
5) Restarts the computer when the restoration is finished.

2- If that doesn't work then try this:
