If you can't positively identify the ICC file then leave well enough alone. The idea of renaming it is to prevent any application from using it (temporarily) while you fault find. Better than deleting it because you can always restore the original name.
Another way into colour management is to right-click on your Desktop and select "Screen Resolution" (hope that works for Vista as well as W7). Click on "Advanced Settings" and, with luck, you'll end up in a dialog box with a "Color Management" tab. Make liberal use of the online help (I won't be able to lead you through it, I'm afraid) and you may be able to remove or replace your current colour profile.
Oh, and maybe Photoshop CS4 APPCRASH @ Startup Vista 32bit
will be of interest.
