I'm able to write to the Eprom using NVFLASH but the problem is when I reboot the flash fails presumably because Windows detects an error on the card (43) and the only way to get the driver to "work normally" is to right click on it in device manager, disable then enable it
Is there any way to make the flash update without having to reboot the laptop?
So frustrating - I think the previous owner tried flashing the GPU and cocked it up

Any help would be very much appreciated
