I have Windows 7 the 7068 build, and NFS UC does the same thing to me. I'm wondering if there is a DirectX rendering issue. The game performed flawlessly in XP and Vista x64. I have found that CoD5 also freezes about 20 minutes in, that was one time so I'll have to try that again. CoD4 booted me from online because of a PunkBuster initiation issue, so I'll have to try single player mode and check my settings with those two games.
With NFS UC if I press the start menu key to go back to desktop and click back on NFS in the taskbar, the video advances a little... catches up... but then freezes again. If I continue this process, I eventually get the BSOD. I really like NFS UC and don't want to go through the process of going back to Vista.
Is there a NFS safe mode? I did notice that windows 7 also changes the refresh rate of the monitor, have you tried 800x600 or a lower setting? That is my next step, but I have to change the setting in the game too.
Video drivers
Systems which use XDDM drivers may completely stop responding in certain scenarios. The computer will not respond to CTRL+ALT+DELETE and you will have to cycle the power to restart the computer, with the attendant risk of loss of unsaved data.
Some activities which have been demonstrated to trigger this issue include, but are not limited to:
- Using Winsat.exe or using the Rate and improve your computer’s performance tool.
- Changing multi-monitor configurations
- DVD or other video playback
To avoid this, do not use XDDM drivers, but find an appropriate WDDM driver instead. If your video chipset does not have a WDDM driver (such as the Intel 915), use a VGA driver or an GPU that supports WDDM drivers.
If this issue occurs at setup, either avoid unattended setup or uninstall the XDDM driver and use a VGA driver until setup is complete.
The above came from

and the beta release notes download
I tried installing all versions of DirectX with the same result. Microsoft Flight Sim X works perfect... imagine that. The NFS patch does not address this issue, I already have installed it.
