MSI GT780DXR to Dell GTX580m

[Jaheth]

I can't get the card to work with my GT780DXR.
It's a Dell GTX580m.
Ideas? I edited the .inf files on the driver, but the install gets an error part way through.
Regards,
Jah.

New information:
Hello All,
In my MSI GT780DXR I've recently installed a Dell GTX580m. Flashed the vBios to MSI and installed the drivers fine. Bought some quality thermal paste, applied it correctly (after lots of research and reapplications).
However, when playing the latest game I have (Wildstar), the card heads toward 75 degrees celcius then reboots the computer. After experimenting with various thermal paste applications, it can stay under for a couple of minutes with the fan at full, but always restarts.
My previous video card died playing this game...
Thoughts or theories, anyone?
Regards,
Jah
