You're talking about a TCD652160, correct?
(look on the back at the sticker where the power cord plug in for the model number if you didn't save any of the packing or paperwork)
That model is among those TiVos (and many, many other consumer electronics devices from about the same time) which are prone to having power supply problems due to "capacitor plague".
The good news is that anyone who can do simple soldering can replace about $10 worth of parts and fix it.
However, if you're still running the original 160GB hard drive, it's getting a little long in the tooth and could be going bad as well.
The good news is that you can replace it with a 2TB drive for under $100.
Amazon currently has the WD20EURS for $95.
You will need to remove the drive and hook it and the new drive up to a PC (or in some cases you might be able to use a Mac).
Next time it reboots and is steady for a moment, go into the "Messages and Settings" sub-menu, then into "Account & System Information", and then into "System Information", and see if you're running version 11.0k or 11.0m of the software, or maybe something earlier, like g or h.
If it's not running "m" yet, it may be attempting to switch (which requires a reboot) to the alternate boot partition set to which it has already downloaded and written "m", and not being successful for some reason.
And tell us which cable company where and what kind of cable cards and whether you have to use a Tuning Adapter to get the cable company's Switched Digital Video channels.
And it's not impossible that you have both power supply and hard drive problems.
In order to open up the TiVo you're going to need a #10 Torx bit, and at some point you may need a #8 and a #15 as well.
Lowe's may have similar items, but the listings on their web site seem designed to specifically hide from me the details for which I was looking, and Sears' site is hopelessly broken, so you'd be better off dropping by either of those in person.
