Computer just turned off??

[Cornholio]

Hello all!
Happy new year!
So, today I left the house and left the computer on.
When I came back, to my surprise, it was off. No one in the family had touched it, nor had the light gone out.
When i turned it on, the Vista "Windows did not shut down properly screen came up". I just told it to boot normally.
I looked in the event log, I couldn't find anything, but I did find this log that was from after the crash:

(Some things are edited out for my own privacy. If anything that is edited out is needed, I can provide it.

It said this (in spanish, my os is spanish)(Google translate):
Timer initialization failed precision event a BIOS configuration problem.
The operating system will use another available platform timer timer instead of high-precision event.

Contact your system vendor for technical assistance.
Initialization state: 1.
it said something about HAL.

Any thoughts? Comments?
Any help is greatly appreciated!
Thanks to all in advance!

If its a one off, its just Windows throwing a wobbler.

Happens on a regular basis, check temps, psu, ram, caps on motherboard.

Is the power management set to put the system into standby or sleep mode after a set period of inactivity?

seems like you got hacked or someone was pulling a happy new year trick

TEST YOUR HARDWARE, if you find nothing, ignore it

also - standby for desktops never really works - disable it

 

[ace700]

check to see if you have a virus or trojan

Yeah, I think Windows pulled a joke on me.
But i did see that the hard drive temp (before the shutoff) rose to 54ºc.
I think that caused it. I added cooling to my hard drives, they stay at a stable mid 30ºc range.
HAsn't happened since Thanks to all!
