This question already has an answer here:

I recently installed a nvidia graphic card P-1200, which is a low profile graphic card.

If I leave my machine unused (i7-4770 chipset) for sometime like overnight, any activity leads to freezing of the machine.

On pressing ALT+Crtl+F1, I enter the terminal mode but I am not able to login as I see:

blk_update_IO error

On manual restart many times it takes me to initramfs screen, where I have to run fsck on my linux drive to fix erroneous inodes.

Any help/suggestion will be appreciated, as I fear loosing my work.

Is it possible that the hard drive is dying? Atleast on running a hard drive check from the boot menu, does not show any problem.

Output from smartcontrol is here :- smartctl output

  • Hi David, no this is different. – Schumi08 Mar 31 '17 at 11:31
  • Such errors could be the drive starting to fail. Using tools such as smartctl one can check the SMART data on the drive that can inform you if there are errors on the drive. – Colin Ian King Mar 31 '17 at 13:06

    @Schumi08: The relevant log files are still the same which is why I suggested the linked question as a duplicate. – David Foerster Mar 31 '17 at 16:27
  • Colin I have installed smartctl, so hopefully we will get to know if disk has some issue or not. Between does anyone suspect low profile graphic card or its installation to be the cause? – Schumi08 Apr 6 '17 at 11:04
