This seems rather to be a hardware problem (if "stuck" in this case means hanging or spontaneous rebooting) - this can be caused by:
- a problem with one of the RAM modules
- a problem with the motherboard
- bad ventilation leading to an over-heated system
It is certainly not a problem of the default Fedora 10 install, otherwise it would happen to everyone who uses it.
