Last night I turned off my computer before going to bed same as any other shutdown. This morning i went to boot it and near the end of posting asked me to boot from CD rather then boot from a hard drive. After trying to reboot with no success i went into my bios and checked my boot order. Upon inspection of which hard drive it booted from i discovered none of my HDDs were recognized in my bios. After a in bios reset and a jumper on MB reset i am still failing to recognize my HDDs. I am afraid i fried my Motherboard HDD controllers. For reference Hdds are a seagate 7200.11 500gb (failtastic) and a WD caviar black 750gb, motherboard is a gigabyte GA-ep45-ud3p
all i can say is swap cables, try one drive at a time with out any cd rom pluged in, check if your sata ports are in ide or raid mode. go grab a pci sata card and see if that works, if it does then its your MB.
