A month ago, I posted and received help regarding a failed power supply, thanks Michael!

A week ago, the unit rebooted itself again while watching a recorded show. It did that roughly once a day for weeks (if not months) before the power supply went.

So, I followed other advice I've seen here in the forum, and I ordered a UPS.

The day before the UPS showed up, the heat in my house went crazy (bad damper) and it hit 97 degrees before I got home to turn it off. The HDVR2 was "buzzing" at that time.

I unplugged it overnight, and the next day didn't turn it on until the UPS arrived. It works perfectly, but it's still buzzing. If I press on the top cover, it becomes more muffled, so whatever is rotating or vibrating inside, is causing the cover to "buzz".

Any ideas what it might be, and could it really have been caused by the temp in the room being 97 degrees?

Finally, after installing the UPS (on Friday), the unit indeed rebooted itself again today during playback. That can't be good, and it was happening before my heat went crazy as well, so I'm sure it's unrelated. What might the cause of that be?

Thanks in advance!
