Illustrator CS6 strange crashing behavior

Question

Hello:
I upgraded to CS6 from CS5 today and am noticing some odd crashing behavior.  It occurs most commonly when I'm using the navigator panel, either while zooming or moving the image.  But I've also gotten it while using the Hand tool ( with the navigator closed) and while just drawing with the pencil toll or line segment tool. I don't get any error message except that "Windows has detected a problem and is shutting the program down" message. I can't find any other crash report or problem notices ( Win 7 Home Premium 64 Bit).
I tried updating my video driver ( AMD Radeon HD 6450) and also updated the driver for my Intuos 4 tablet. That didn't help.
When I reopen illustrator, my saved workspace comes back ok, but everything is reset to defaults. For example, the rulers will come back on and any changes to tool attributes are reset to their default status.
One other thing the first time I opened CS6 after installing I got a message about Windows needing to make some registry changes.I followed the directions in the dialog about letting Windows fix it and CS6 has started ok afterward. 
Could this behavior mean my install got corrupted somehow? If so could that be the cause of Windows not "playing nice?"  Incidentally, Photoshop CS6 is working perfectly.
thanks for your help..
System details:
Windows 7 home Premium SP 1 64 bit ( fully updated)
Intel Core i5 2300 CPU 2.80 Ghz
6 GB RAM
AMD Radeon HD 6450 video card

mjmdvm,
I read with horror the things tech support told you and did to your computer.  There are good tech support people and bad tech support people (at any company, not just Adobe) and you seem to have run into two bad ones.
My suggestion would be to create a new administrator account in Win7 and see if IL CS6 works when you're logged in to that account.
Unfortunately, your tech support sessions have probably hosed your old account (and possibly the IL CS6 installation) beyond repair -- you've already noticed the weird command prompt and sluggish boot times of Win7, now, which are symptoms of "not good".
To recap the tech support errors -- Win7 manages memory exceptionally well, so there's no question of other apps (like Office) "hogging" resources.  That is an outdated concept from the ancient days of personal computing.  No need to modify registry entries, either -- simply running IL CS6 "As administrator" from its icon is all that is necessary.  It was also a bad idea to modify security permissions -- Win7 has excellent security features enabled by default for a very good reason:  they protect you from malware.  Modifying those permissions haphazardously is detrimental to your safety.  You'll like the extra RAM, anyway, but 6Gb in Win7 x64 is sufficient to run any application and will not cause an internal application function (the Navigator window) to crash the app.
Sorry for the long diatribe, but I once worked in tech support for a small software company and one of my pet peeves is bad tech support.
I wish you success in resolving your problem.

P.S.,  I'm running IL CS6 on a Win7 Home Premium x64 system.  Other than having to run it "As administrator" because of a problem with Save For Web, leaving the Navigator panel open does not crash the app.  I do have 8Gb of RAM.
