Windows 7: Kernel Power 41 - playing Planet Entropia

Kernel Power 41 - playing Planet Entropia

Hello, Please help me with a problem i cant seem to resolve.

When playing Planet Entropia (widely know as planet calypso) I am getting sudden unexpected shutdowns. This happens when in windowed mode or fullscreen.

The computer is a SONY VAIO Laptop (more detailed specs at bottom of page)

What happens...
Screen goes black, computer restarts.
This crash does not produce a MEMORY DUMP file.
I have collected the information explained in the posting instructions, you will find the zip file at the bottom of the post, along with my computer specs.

This has been happening for almost a month now.

What I have done...

Changed Nvidia drivers from 182 to 190
Then on the 15th of April I factory reset the whole computer, ensured i had all updates from sony support (including a bios update)

The system now has the latest sony recomended driver for nvidia

Turning off C3/C6 support in the bios seems to have no effect.

I have also monitored thermal properties, and all temperatures appear to be well within normal operating ranges. (using OpenHarwareMonitor)
I have also, cleaned the copper heatsink and fan assembly, just in case.

My Planet Entropia installation has been checked and is valid.

I have also read the microsoft article about Kernel power 41 located at..
Description of Windows Kernel event ID 41 error in Windows 7 or in Windows Server 2008 R2: "The system has rebooted without cleanly shutting down first"

This article only leads me to another question...

As this is a laptop VAIO computer, and the power supply is external, is it possible that a problem with the power supply would translate into the computer? (or would the computer just switch to battery?)

Ant help you could give me with this error would be greatly appreciated, so far sony support have not responded to my email, even though it has been well over 48 hours since i sent it.

Thank you for any assistance you can offer.

How old is the system? If it is still under warranty, you may want to send it in. Before you do, check software conflicts and check for viruses/malware.

If the system is no longer under warranty, proceed to hardware checks.
  • If you are overclocking any hardware, please stop.

  • Monitor temperatures during the following tests. I know you said you do not think temperature is a factor, but some of the tests will stress your computer more than typical use, so it is best to make sure the system does not overheat during the stress tests. That way, if temperatures start to get above the maximum ratings, you can stop the test.
    Use the following programs to monitor the temperatures.
  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).

    For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
    Once these steps have been followed, it is safe to remove and replace components within your computer.
