Help Soft reset and Milestone 2 shutting down

[Phoebus]

Hi,

I've a Milestone 2 running Gingerbread and at the moment I have to take the battery out, on average, twice per day due to it freezing up. Is there a way of soft-resetting from the hardware keys? I have seen pages saying I can use Ctrl-Alt-Del (well shift-Alt-Del) but this doesn't work for me.

Also, any ideas why it keeps crashing? I have a few apps on my homescreens but got rid of a lot, and I have task manager auto-kill apps. I can't seem to make sense of what I am doing wrong - some days it is fine, others I have to keep taking out the battery as it won't even unlock or work even after a reboot.

Thanks.
