I found this. Lets see if it works first.
Sometimes services and apps you install on your HTC Droid Incredible can interfere with its functionality. If you’ve reached a point where the phone freezes at startup or malfunctions in a way that you can’t remove the problem, Safe Mode is the answer. Booting in Safe Mode will load only software and drivers from factory defaults. This should allow you access to remove whatever ails your smartphone.
1. Turn the device off. If the power button doesn’t do the trick, remove and replace the battery.
2. Power the device on.
3. When the logo appears, press and hold the Menu button.
4. Continue holding the Menu button until you see the home screen.
The words Safe Mode should appear in the lower left corner if you performed the steps correctly.
If this works, I would start deleting apps, newest download first.
