Dlink 624 constant resets

I have a dlink 624 RevC router that sometimes has spells of resetting
constantly (minutes to hours at a time). I downloaded and installed
the latest and greatest firmware because it mentioned something about
fixing DHCP reset problem but did not help. Anyone else having this
problem?

No one responded but that's ok. I'll be 'throwing away' my Dlink.
Not only does it have the problem stated above, documentation is
usually six months behind the release of new product features.
Organization of the screen menu is
confusing and senseless. They have an option of saving your settings
before you upgrade so you don't have to reenter everything but it
doesn't work.
It's just crap. Probably the last dlink product I'll buy although I
use their pocket print server and that has worked flawlessly.
