Yeah, I don't think it would be a power issue. I wished there was a
bootable disc or USB flash media to test this issue out with full video
acceleration with videos.

Perhaps more heat generated due to more intense processing activity? Or
the extra current draw exceeding the power supply's ability to
consistently provide?

But a 650-watt power supply really should not have such problems.
Of course, it is possible for the voltage/current on a specific set of
rails to be out of spec while the rest of the thing is fine. A bad
connection could do that. But I would not fool around with a power
supply unless I knew exactly what I was doing, even with the thing
disconnected from the mains.

Puzzling.

Interesting. I have had this Corsair CMPSU-650TX 650 watts
ATX12V/EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active
PFC power supply since end of 2010 when it was new. Also, why
would having video acceleration cause these rare lock ups when
having none doesn't?

Hi,

I have seen posts on AVS by a resident HTPC expert suggesting a
flakily
power supply may be the cause of the problems like you are seeing.

Might expose your problems to more experts with better advice.
