Well, at first I thought Might be overheating, Given that its new. This really shouldn't be an issue. But what videos are you streaming, If off sites like Youtube, FLV vidoes tend to use a fair amoun of CPU usage/load. Which could bring on the heat. You can download various free tools to monitor your CPU core easily.
It only seems to happen at: Narutoget.com or Bleachget.com... as those are the ones I go to most often. But those sites worked fine before..
If its solely caused by the videos itself. IT might be a hardware/driver issue. Either graphics or harddrive. they usually Give blue screens. But Make sure you update to the latest flash version and update your drivers.
I am fully updated, and like I said, everything is brand new.. so unless the HDD was bad out of the box, I don't think that's it.
Also, Can you give more details on the tests you done, and how it restarts. Does it go straight to the bios screen, does it pause? Just little quibbles like that could give a few clues or leeds onto what is the cause.
I ran a utility program, and it said that all my hardware was fine, cause it ran various tests. Now, it is a bit old, so that may not be completely reliable, but it seems to be. It goes to BSOD, because I disabled automatic restart to see what would happen. When that was enabled, it just restarted, no warning, and went straight to BIOS.
I would leave it on for awhile with, lets say you are running a program to accurately work out pi. To use up your cpu resources or any CPU intensive task over a long period. And see if it shuts itself off and if it does. Leave it ideling and see if it restarts on its own after while.
Nope, only video streaming does this. I can leave it on all day, and nothing will happen.
I find it being caused by youtube videos a little funny :S.
Surpriseingly, Youtube works just fine.. go figure..
seems you posted while I was composing mine,
That's okay, your questions were relevant, so I answered them.
Anyway, All because its new won't guarantee its fault free. If all else fails. I would see if you can send it back to be checked up on under the warranty.
I know its no guarantee.. but I built the thing myself, so I can't really just send it in, ya know?
