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 week , I'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)
