Windows Startup Plm!

Windows 7 failed to start. System Restore - 0x8000FFFF (Catastrophic Failure)
A recent hardware or software change might be the cause.

Did you add any hardware or software just before the problem occurred?
Were any Windows updates just installed?
Had you already tried to do a System Restore?
 



I added software before it collapsed. Really upgrade one program not Windows. I did tried to use System Restore - still not working. I plan to use "Safe Mode" to remove the program but I can't because not working so.. What should I do?
