If it is occuring after a complete restore, I would have to suspect that it is not seeing all the ram it needs. You might want to try replacing or reseating sticks.
A standard installation shouldn't cause such issues, but you can try some clean boot troubleshooting techniques to see if it is related to anything loading at startup.
