If I never had to restart, sure. I have to restart my laptop weekly at least. Heck, it locked up twice last week opening Diablo 3 forcing a hard power cycle. My phone gets restarted less often but still gets into odd states where a reboot is needed.
tangential, but check out that your power supply is ok, that's the second most common source of random lockups during load (I assume drivers are up to date, that'd be the first)
