Restart - No BSOD no error nothing?!

[Jackal]

Hi guys, i got my self in a kind of predicament here.

My PC will restart with no BSOD or error logs anywhere - screen would go black, keyboard lights go off, and it would restart as if i had pressed the restart button.
however i did manage to get this from event viewer

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Event ID: 41
Source: Kernel-Power
Task Category: (63)

it seems to happen when i open Adobe After effects and i scroll the bar to view the frames (mostly) - but it has happened without after effects but it seems i can trigger it by doing what i do in after effects

Any help will be GREATLY appreciated


System info
i7 920 @ stock
6GB ram @ stock
GTX480
EX-58-Extreme mobo - gigabyte
Windows 7 64 bit

Hi Jackal,

Just to check : this never happens except when you use Adobe?

it only happens now using after effects

i did a memtest passed 11 checks with 0 errors

CPU overheating is not the issue
PSU doesnt seem to have any issues

When im in after effects and import a video, and i move the timeline cursor around to view it, it would restart my PC.... really strange, any help?

so i did more messing around, i disabled open GL previews in after effects and it seemed to have stopped the restarts for now... ill keep trying to provoke it to see if it works.
