Photoshop CS6 freezes upon opening

Question

Running CS6 64-bit on a Windows 7 machine. Everything is updated, and it was working fine yesterday and every day before for the 2 months we've been running it on this machine. New today:
Open Photoshop and it opens the window but you can't click anything. It's like a pretty image file of what your PS experience would look like. Can't close it because even the little red X doesn't register as anything. Have to force quit from Task Manager. Restarted the system (full shut down, pause, start, not just a system restart).
Deleted the Preferences file and restarted the system. That kind of helped. Now we can open and click around for about 25 seconds. That's enough time to change my performance preferences and close the program before it freezes. So I did that and restarted the system. No change. I can also open the "open file" dialogue, but the second that opens, everything freezes back into that pretty picture of what it would look like if I were to be using PS.
Nothing else on the system freezes while PS is frozen. I can do webby stuff and work in other Adobe programs, check my email, dig around in my explorer, pretty much anything I want as long as it isn't PS.
Exception: If I open Bridge, I can use it just fine until I try to open a file from Bridge in Photoshop. Then both programs freeze until I force quit PS. After that, Bridge is happy again. If I try to use Bridge to run a PS process, I get the message window that PS is currently running another process, would I like to queue this one. No matter what I hit, everything gets angry until I force quit Photoshop.
I spoke to a nice man on the customer service line who was very good at reading suggestions like delete preferences or completely reinstall the suite from his list of fixes, but didn't seem to understand at all what I was asking him. So I turn to you, oh forum of knowledge. Anyone know how to fix this? We've reinstalled video drivers. We're currently trying running a repair off the Windows OS disk.
We would like to not have to uninstall and reinstall the whole suite. Everything else works great. AE is happy, Illustrator is happy, Bridge is happy so long as we don't make it talk to PS. If there's a way to just reinstall or run a repair on PS without affecting the rest of the suite, that would be an option too.

Hello,
I've got similar problem,
When I turn on my compagny computer everything is alright. Photoshop CS6 13.0 x32 start correctly. i can work on picture as expected.
But during the day, Photoshop doesn't want to open other file (any file).
I can work on with a picture that still open and save it, but can not open anything else.
Restart Photoshop doesn't work.
I must reboot the computer to correct this and open other file.
I'm on windows 7 SP1 with administrator rights
No plugin installed, I'm a beginner with Photoshop
Can you help me please ?
Thanks
