W500 Screen flickering - video available at youtube

[vipervr]

Out of the sudden, my W500 with Vista Ultimate 32 boots up with screen flickering nonstop http://www.youtube.com/watch?v=dTucGPj9f7M.

Boot in VGA mode won't work either, but screen seems to be okay in Safe Mode only.

Managed to boot via Last known good configuration once and it worked fine for that day but after the next restart, the problem reappeared.

Has anyone here faced this problem before?

Thanks.

It requires a login...

The screen starts to flicker even before the login icons appear on screen. Though i can see the login screen just fine in Safe Mode. I'm thinking my Vista might've been corrupted somehow...

Marin85,

I don´t have a W500 but I can tell you for sure that this is not a normal behavior. If you are sure that this problem doesn´t appear in Safe Mode, then I would rather lean towards a software problem (hardware issues are always possible though). Did you try installing a different video driver version? Maybe it is just bad driver (install), maybe not... But that´s the most simple thing you could start with and (un)check for a problem. You can do this from within Safe Mode, but I´m not sure if you have to log in as admin. Installing the driver will definitely require admin rights though.

Good luck

removing graphic adapters (both built in and discrete) drivers in Safe mode didn't help. I resorted to system restore instead then things were back to normal again.

thanks anyway.
