I have an Intel i3 core processor in my computer. With the Gigabyte GA-EP43-S3L motherboard since my computer was working well but as I installed new bios through BIOS for my Gigabyte GA-EP43-S3L my computer is not working (black screen). Why dual bios doesn't solve my chief Bios. So anyone know how to fix this problem. My present Bios F8 didn't functioning well. Ubuntu as well as Vista in my computer also didn't wake up without pressing power off power on. So what to do in order to solve this problem in my computer? Please let me know through your suggestion.
