Y700 Screen Flicker gone, but won't boot

So I had the issue where the screen would flicker incessantly, I booted into Safe Mode, unsintalled the graphics drivers and all that ended.  However, Windows Update downloaded an update to the graphics card, which consistently failed to install.  This would also cause the laptop to reboot, and start the whole process over again (after about half an hour).  I tried to bypass Windows Update and go right to the device manager and update the driver there.  Windows did download drivers and I believe the system again rebooted while installing them.  Now when I boot up, I see the Lenovo Logo, then the swirling circle of dots (after the Lenovo logo disappears) just swirls constantly.  I can not reach Windows at all to go back into Safe Mode even.

Re: Y700 Screen Flicker gone, but won't boot

Hi there, Exanth          -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

Most often, these types of problems are due to a software conflict or a pre-existing issue that simply wasn't brought to light until the Windows updates started installing. Much more rarely they're caused by a mistake on Microsoft's part regarding the update itself.

 

Do hard reset & restart the system.

 

Update us how it goes.

 

 

 

 

Regards,

Well a hard reboot did allow the system to finish its update and boot.  Of course now I'm back where I started with the blinking, I'm going to try and disable device updates, uninstall the device driver and download the driver instead of having Windows update it.  Crossing fingers.

I have the same issue with the same model.  I think it's coming from an AMD driver update.  How do I perform the hard reset you mentioned?

Any difference if you start using the Novo button instead of the power button?

 

Update us how it goes.
