Hi,
Usually it means cpu is not properly recognized and running at some odd clock frequency. But it may allow you to run Qflash?
Ask Gigabyte to send you an updated bios chip to swap out with your current one,
Do a google search or ebay - there are people that will sell you bios chips for your specific mobo with the latest bios,
Buy the cheapest supported cpu, reflash, then flog it on,
Would your supplier flash it for you, thats, if you bought it all from the same place?
