Pls help, my desire stuck in fastboot-recovery mode

[Guest AliminHMFFC]

Pls Help. I m a newbie… My desire stucks in ClockworkMod recovery mode. When I click reboot system now, it will enter to the white screen (fastboot) and will not start up further to the home screen.

Rooted using Unrevoked 3, used Titanium backup to back all apps, performed 3 wipes (data/factory reset, cache partition, delvik). But when I tried to look for my .zip file, it wasn’t there, so clicked on reboot system now. However this led to my device doing a repeated booting before I m getting stuck in the recovery-fastboot screen. How do i at least get my device to go further to home screen? I cant use it now.

My Desire is HBOOT 0.75, Android 2.1 update1. Appreciate kind help on this. PLs let me if more info/background to the problem is required.
