If it is of any help I have been having this same problem ever since the the 3.8.0 kernel came out. When I first starting having this problem I was running 64 bit Xubuntu 3.04 with the nouveau drivers. I just figured that it was a problem on my system. So long as I booted using the 3.5.0-28 kernel I would never get freezes. I just did a fresh install of Xubuntu 3.10 64-bit on a new HD and I could not get the system to run more than an hour (often less) without a freeze requiring a hard reboot. I installed the nVidia 304.88 driver (nVidia current) last night and I have not hand any freezes yet (fingers crossed).
