My first check would be video drivers if this is a newly built computer. If it is a computer that has been running a while and the problem suddenly appeared I would reseat the RAM and attempt to boot into safe mode, suspecting a virus infection.

Startup repair won't run


"Unmountable boot volume" this problem is your hard disk partition which is failure to recognize & identify the operating system running on the hard disk. Reformat your hard disk and put another operating system to run again your computer.

Computer only displays vertical lines and pink background.


Most likely an issue with the Video Card or Video driver.
* Boot to safe mode by tapping F8 while starting up the computer. Selected safe mode with the keyboard and hit enter. Login to your user account. You should see the words “Safe Mode” on all four corners,
* Open device manager – Right click “My Computer” – Select “Manage” – Selected device manager from the left. Under display driver, you should see your vide card listed. Right click on it and select “Disable”.
Now restart your computer and if this resolves the issue, then the vide card may be at fault. You could also try updating the video driver.
Do let me know if you get this far.

Vertical, pencil-thin blue line appears after 10 minutes of viewing (any source)


I would suspect a connection breaking down as the set heats up. A shop will probably have to put the set in a stand to hold it while they check for loose connections or defective components inside. Not a DIY job by any means. If this line went completely through the picture either vertically or horizontally and stayed there then this would have indicated a failure in the Panel itself. A thin Line any where on the screen consisting of one pixel in width is a Panel Failure according to Hitachi.
