Resolution changed and can't be returned to original resolution.

I am beginning to believe this is a hardware issue.
Last night, I booted up an old hard drive I use for experimenting. It
has Ubuntu 6.06 on it but has not been updated in several weeks+. It
boots as normal and has normal resolution (1024x768).
This morning I booted up my backup server (the original machine giving
me problems) and I noticed that the login screen looked normal (not
640x480). After booting the screen was 640x480 but going to System >
Preferences > Screen Resolution, all the options are back and I am now
able to change the resolution back to 1024x768 85Hz.
I then tried rebooting my desktop and it two has returned to normal!
Maybe I have a few ghosts in my machines.
