This has happened only once, but i am afraid that it will become frequent. The computer just shutdown while i was on youtube. It almost immediately came up with the"system did not shutdown correctly" on it's own and I clicked" start windows normally". Power was still being supplied to the components though.

Here are 2 long event logs that were logged at the time of the event

I do not beleive the problem is the PSU. I hope the problem is software related, Not a hardware problem
I am not overclocking anything. I have not changed anything in the system recently either.

Any educated help would be greatly apprecitaed. Sorry the thread is so long.

HT watchdog timeout means that some device didn't react when the CPU tried to access it.

Don’t think it could be memory related as it doesn’t access through the HT bus.

Try removing or disabling cards/devices and see if the problem vanishes.

That’s the best i can do.
