Welcome to Android Central! Did this start recently? If so, consider uninstalling some of your recently installed apps, in case they're causing problems. Another thing to consider is to unmount your external SD card (in Settings>Storage), remove the card, and then reboot, since corrupt cards can sometimes cause problems.

Ultimately, you might need to consider doing a factory reset: HTC Desire SV Support - Resetting HTC Desire SV | HTC India
