You get Event ID 41 and no detailed info? Does the system go into standby after 20 minutes?
Here are the details.
I found this http://support.microsoft.com/kb/2028504#method3
Scenario 3 sounds most similar. It gave me a few things to try, and seeing if any of them fix the problem one by one.
-I'm starting with reverting my overclock back to default.
-If that doesn't work, I'm going to try and split my plug ins from one outlet to two.
The other 3 I already ruled out, so if neither of these fix the problem I'm going to try swapping out or testing the power supply.
Thank you for your help by the way, I completely forgot about the Event Viewer.
