Any new solutions out for the following problem yet?

-Hard lock of the computer about 80% of the time when: Buying items, Hacking, Taking a picture, Using Gene Banks, Uprgading a weapon. Game runs just fine when in the game world.

Ive tried:

Running in DX9
Running in DX10
Running in Windowed mode
Disabling "Tablet options" (in Vista)
Running with lower graphical settings
Running with lowered Audio settings
Downloading (and installing) FULL DX10
Running with/without SLi "on"
Running in Windoes 98se
(okay, maybe that last one was a lie)


...So I have basically quit playing as every time it locks the machine it also (of course) resets all game settings and key bindings. So, are there any newfangled ideas out there for this problem(other than to never buy stuff, upgrade stuff, etc)?

Basic Specs:

Vista64bit
E6600
