This question already has an answer here:
So I have a problem with my asus computer: everything went just fine until today, my computer shows me the grub menu when I start up like it usually does. But when I choose a version of linux the only thing I get is a purple screen or a black one if I use the recovery mode.
I have been using ubuntu 12.04 for about a month and I did not download a single update the day before it started to act like this. It was also running perfectly fine on start up until today.
I tried to replace quiet splash with nomodeset but that didn't help, running an older version of linux didn't help either, as I have the same problem on every version.
I have an
8 Gb DDR3 Ram
Nvidia GTX 560 graphics card
Intel i7 quad core processor
(Someone posted a similar question here: Ubuntu 12.04.2 LTS boots to purple screen but nobody answered :/)
Edit Boot repair didn't solve the problem, here is the link it gave me: http://paste.ubuntu.com/6033493/
Second Edit: ctrl alt delete who worked before the boot repair doesn't work anymore... :/ (I could use it when I had the purple/black screen)
3th edit: The Grub commandline works, so maybe it's a problem with graphics? (Even though I didn't change anything when I last used my laptop on Ubuntu..)
Last edit: Seems like this was marked as a duplicate, the answers provided didn't solve the problem at all.. As I couldn't find the source of the problem I reinstalled ubuntu... (Wich completely crashed my computer, due to a fatal error while trying to install the grub, it couldn't find the device.. But that's not part of the question anymore :).)
But thanks for your fast answers! :)
