Problem: Lenovo idea-pad Z570 screen blank(no power) while startup after windows 7 logo flag

Hi ,
This is Rahul,I brought a new laptop on 06-12-2011,Lenovo Ideapad  Z570 core i3 . It has a  pre installed Windows7 home basic , laptop worked fine till yet , not much of  computing  problem , but  from this weekI'm noticing  When booting Windows 7 x64 on my  z570 , right after the "Starting Windows" screen , Laptop screen goes blank(no signal/power as i've connected an external  lcd desktop monitior to it , and same thing happen 1 min signal out) for 1 minute(or1 ½ min)  typically.  After that , the logon screen appears as normal and everything works normally and but  shutting down is also unusually slow( like 3 ½ mins). I have uninstalled all unnecessary programs and also msconfig boot load only MS application  ,updated the bios, graphics , camera drivers  from lenovo support . check  it  all . Nothing seems to be curing this problem .  

 pls help asap.

 

p.s check problem video : http://youtu.be/cZJz6wuYjLs      (check screen goes  no signal for 1min)

I don't have this problem, but because it appears after Windows has started to boot up I would put the blame with Windows doing something funky. Seeing as you've updated drivers etc, I'd personally backup my data and re-install Windows / recover to factory settings using One Key Recovery in this case and see if it fixes it.
