The other day my laptop running Windows 7 Home Premium 64 bit stoppped booting. It would not load in Safe Mode, Last known good config, or any other way. I just kept getting a black screen with a mouse cursor sitting there and never got any further. Task manager wouldn'r come up and the onl way I could stop it was by holding the power button until my laptop shut off. Using the Windows 7 DVD, I ran the repair option which seemed to fix the problem, however a lot of my MS shortcuts refuse to work. However, if I manually navigate to the executable or create a new shortcut they work. When I click I get Invalid Shortcut with a Pop up that says: TRY\MACH. I uninstalled MS Office 2007 and reinstalled but it did not fix the problem. The same thing happens when I try to click on an excel or word document. I am perplexed and have never seen this before. Any help would be greatly appreciated.
