Windows 7: Kernel-Power Error 41

Hey everyone,

This is my first time posting here, but I have lurked around and read all the threads I could find in regards to this error. I know it's a general error, but I plan to provide as much information as I can.

For the past 4 months, my desktop has been shutting down during games. It doesn't matter what the settings are on, but it simply shuts off and reboots without any warning.

This happens approximately 45 to 80 minutes into a session.

I have recently replaced/tested:

Replaced Motherboard
Replaced PSU (3 times)
Replaced Graphics card
Reinstalled OS twice
Cleaned the entire case
Re-applied thermal goo on processor
Checked the fans, and made sure they worked
Opened my case and placed a fan on the side to create circulation
Replaced ram
Ran memtest on new ram, no errors

I have no clue what steps I should take next, and I can only assume thus far that I either have another faulty PSU or my processor is starting to go.

I have attached my system information as well as my system tempuratures/volts.

Please let me know if there's anything else that would be helpful.

Thanks!
Steven

Any and all suggestions would be very appreciated! I'm out of ideas on what I should do next.

Anyone?
