I'm not sure how much background to give. If it's too much or too little, I'll edit the post later.

(Also, it seems that bug-report questions - possibly including this one - might not get answered here. If true, where should I post this?)

I have Ubuntu 12.10 set to dual-boot with Windows XP. This morning, Ubuntu hung badly. I could move the mouse, but I couldn't do anything else. I had Google Chrome up when it hung; I couldn't click on my other tabs, I couldn't click on anything on the dash; it just didn't respond, it froze up.

This has happened to me twice before; the first time, I waited nearly half an hour, and it didn't unfreeze. So, I had to do a hard reboot, which worked both times. So I hard rebooted again - held the power button down till it turned off - and when I turned it back on, it didn't even get to the login screen. When I try to log into Ubuntu, it flashes an underscore cursor on a command line of sorts for a while, and then the screen goes COMPLETELY dead. Even this one dead pixel in the middle of my screen turns off.

It's possible I have a virus, but it could also be some process that broke the computer when it hard rebooted.

I can still log into Windows - that's where I'm posting this from now - but I am so far out of my depth it's not even funny. Help!

It looks like more a problem with a disk than a virus to me.

It doesn't look like I can. I rebooted it twice, trying it; I bound the function keys to their alternate actions when I first got the computer, so I tried it with and without hitting the Fn key before the F1 key - no soap. I also tried Alt-Ctrl-F1; still nothing. When I relogged into Windows, however, it had me check the disk, using what seems to be a standard procedure. IT found a bunch of errors and said it corrected them; but I still can't log in to Ubuntu.

I don't think you should use Windows to check disk since the partitions in Ubuntu are not NTFS.

You could try to check and fix it using fsck from a Live USB (maybe present in Gparted Live USB).

It happened something similar to my machine some time ago. It was a poor cooling of the video card (Nvidia). It didn't happen in windows (dual boot) but when using Ubuntu. The solution was to open the case, remove the video card, clean the card cooling fan and check the card heat sink (have thermal compound at hand), also, it'd be wise to clean the CPU fan. Good luck!
