I recently got an old desktop pc from college and installed Ubuntu on it. At boot, I would get the message:
"Input signal out of range. Change settings to 60hz 1280x1024."
...but ignored it, because after about 5 seconds the OS would boot as expected.

After about a month though, it stopped booting normally and was stuck on the 'Input signal out of range' message.
With a live USB distro, I tried changing the /etc/default/grub GRUB_GFXMODE setting to match my monitor's resolution, but couldn't figure out how to mount the drive to run sudo grub-update so I gave up and installed xubuntu to see if made any difference.
I had the same problem with xubuntu though, but this time I decided to change the grub GFX setting before it could cause any more serious problems. It didn't change the message at boot though, and a few boots later, xubuntu now isn't booting just like ubuntu.

So, what do you think? Is it a hard drive problem or graphics driver or something?

Other stuff I've tried...
I tried attaching another monitor and that just outputs...
"Out of range."

Chip itself on its way out? If you add a video card, does it still happen?

I tried another hard drive with an old version of linux mint installed and got the same issue. Unfortunately, I don't have another graphics card to try out DM's theory.
