So I have this Gigabyte r9 280 windforce which worked perfectly. But then after changing mobo and cpu it stopped working entirely. Like not even the fan is spinning. The die itself is heating up though. There were no smoke, no strange sounds etc. Now is there any way to check if it actually is dead? Its not detected by pc, no video output, fans not spinning, though as I said the die is heating up when pc is turned on.
