Hey guys,

Today I put my computer parts together. I know they are all functional and put in the right places, or else it wouldn't run! However when I turned on the computer, I was faced with this message.

"reboot and select proper boot device or insert boot media in selected boot device"

Someone suggested to me that I should set up my BIOS in a certain way. I made it so that the computer reads CD/DVD first, but it doesn't work. I notice mention of floppy drives, so I disabled it, with no effect. I've been fiddling around with it, but I can't get out of that message. Anyone have any suggestions?

Biostar ta790gxb3 motherboard and AMD Athlon II x3 435 are my mobo/processor.

Other parts if it matters: Seagate 7200.12 500gb hdd, powercolor radeon hd 4850 1 gb, a-data 4 (2x2gb) ddr3 ram, lite-on basic dvd burner (forgot model).

Please help1!!!!
