Specs: Windows 7, 2GB
hello sir,
I'm using lenovo Y500 47Q model laptop.I recently detected a problem in my laptop,when I boot up my computer vertical and horizontal lines appear on my laptop screen nothing goes wrong in windows section. But recently I had format my laptop after that I'm unable to load VGA drivers in it.whenever I try to install in windows 8 the window itself get corrupted or needs repair after booting and in Windows 7 the screen appears black after booting.
I'm stucked in this whole mess and just hope there is nothing major damage in it.If you are familiar to this sort of thing please take me out from this mess.
Hoping I'll be replied as soon as possible and with a positive sign.
