Help With Tivo Rebooting

[Fixit]

My Tivo has just rebooted 3 times in the last 30 minutes, had it had a new a/v drive installed when it was modded last year,
any clues what's needed, live in Perth Northern Suburbs

It is possibly some form of software corruption. Usual way of testing is load up another hard disk (anything from 160GB up to 2TB will do) with a clean install of the TiVo software and test with that to see if the problem persists.
