Modem or provider issues?

The other day, the PSU on my computer apparently up and quit at random and less than a day later my cable modem seems to have gone the same way. Which is unfortunate, considering the lack of technology is killing me right now. On top of that, I can't figure out what exactly is wrong with my cable modem.

In detail, over the past few days I've been having connection issues with my Motorola surfboard modem, before it outright stopped wanting to work. I'd have my connection dropped maybe once a day, and my send/receive lights would both be lit up and flashing constantly, with the online light off. Simply unplugging the modem from power and resetting wouldn't fix it, I'd have to also unplug the coax from the modem before my connection would work again (strange considering cutting power to the modem wasn't enough).

Now, my modem is stuck with send/receive lights flashing constantly and I have no connection. I've tried resetting the modem both physically and from the configuration page, restoring to factory defaults, changed out the coax cables, and switched out Ethernet cables between my router and modem just in case, plus running a cable straight to my computer from my modem. Nothing is fixing it. I've looked at the logs page and I have a message saying "ToD request sent - No response received" and "DHCP WARNING - Non-critical field invalid in response" which from what I know aren't connection-breaking errors. I have "Ethernet link up/down" alternating because of the connection dropping. Upstream and downstream is all normal and how it should be. It just simply isn't working. Is there a specific reason the send/receive lights only would be lit up and flashing that might be a clue to what's wrong?
 
Solution
call your isp see if somehow they canceled your account with that cable modem. (cable modems are set by there mac info) if the info cant be read or someone cloned your modem. your isp may think there two of you. (turned off your modem). isp could have done a firmware upgrade and it bricked your unit. (try downloading the firmware or ask your isp to do a forced firmware send from there end (need a t2 or t3 support to do this). follow your cable lines...make sure a cable box or splitter has not gone bad. check the line on the side of your house and where it comes in from the pole for damage.
