I was trying to replace my sata 1 with sate 3 cables and I believe I accidentally shorted out the mobo. Is there a way to test this out before ordering a new mobo ? The one I have is a Gigabyte "GA-890GPA-UD3H". When I power on I get no video signal from the card (HDMI)or on board through the (VGA port),No beeps whats so ever either. The cpu fan seems to be running a little slow but not positive. I have a Ultra psu tester and everything there seems fine.Similar to this one "http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1647108&CatId=5471"
