Can you get network access to the machine when it gets into this state? If you can't, that suggests the OS is hanging or crashing, possibly in response to going into some sort of power-saving mode. If you can get in, then there are many more possibilities. Firstly, you should be able to kill and restart the X server, which might get your display back without rebooting. Or else you could shutdown and reboot cleanly. As to working out what the underlying cause of the problem is: that's harder. I'd try experimenting with the power saving settings for your graphics display. If you can turn them off as a test, and the machine then survives for an extended period of idleness, you'll have gone a long way towards isolating the problem.
