Just loaded up a windows vista business 64 pc this morning and for some reason no executable files will load, all the startup programs load but it's impossible to get any other file to execute, wmp, firefox, thunderbird, cpu-z, anything, if I click on it nothing happens. If I go into task manager and try to start a program that way it appears in the task manager window and then dissapears a few seconds later. It's the most bizarre thing I've ever seen.
