Hi,

I've got GT780dx ( burned 570M ). I just replaced card, whit gtx675m.(AFAIK it should be the same thing as 580M)
Now, I know some people made it working and its showing GT783 in their BIOS.
I get laptop restarting more often when is plugged in and sometimes on battery, whit Nvidia driver installed , suddenly, no bsod, screen goes blank and restart
If I delete the driver the problem goes away. New video card is DELL gtx675m
I have tried:
MSI GTX675M vBios
Clevo GTX675M vBios
Dell GTX675M vBios
Lowering down GPU clock
MSI GTX580M vBios (whit modded driver)
MSI GTX570M vBios (whit modded driver)
Installing win 10 x64
And I also bought a new charger whit 11A .
I changed Thermal paste.
MSI nvidia driver and dell nvidia driver
Installing Win 7 x64
DIfferent HDDs, SSD
Disabling/Enabling CPU features in BIOS
Also Bought an Modified BIOS from MSI forum, I tought it was a compatibilty issue (Dell GPU & MSI Mobo) , but no success, now I have all the things unlocked in BIOS.
I locked some CPU cores, no success.
I have done 2 memtests, not problem, "Pass Complete , no errors , press ESC to exit."

Here is an IntelBurnTest:
