Lenovo Y50-70 turns on but has black screen

[matrix1999]

Update:  I installed the 1.14 BIOS per instructions and let the system run for about 30 mins or so.  I then went ahead and "upgrade" the BIOS to 3.00 (not 3.03) and it has been running for several hours now.  Happy to report that everything seems to be back on track.

Would it work for Windows 10 too? I too seem to have the same problem..Y50-70 turns on but has a black screen.

Yes it does work for Windows 10.  I was running W10 when the error occurred to me at the time

You are a lifesaver!  I followed your directions step by step including praying and my laptop works now.  I've had this issue for months and months now only at startup.  I never turned off my laptop because of it.  You deserve good karma for all your help,  I know I'm not the only one to benefit from this little tutorial you made.  

Lenovo should give you a job.  Thank you.
