[Error]. Pc reboot. And blue screen. Without sense.

[BlochMarc]

The situation is this:

I can play starcraft II or Skyrim without problems but my PC sometimes reboots on youtube.

Or reboots every time i render (Can I say "render a video"?) a video with Adobe Premiere.

From youtube i see a "bluescreen", from premier simply a reboot.

Can anyone save me?

I don't know if this is the right section. If not forgive me.
