Supermicro x5da8 motherboard - hard drive light stays on



Yes, I have an issue where the hard drive activity light stays on, no video and does not boot. I removed cmos battery and cleared cmos shorting the 2 solder tabs.
I have removed the hard drives, SCSI and IDE cd drive along with Floppy. No change. I removed all the memory and then I hear the beep error.
I replaced the power supply with one that works, used these components in another case with this type of mother board. At one point I could have thought it was booting, I thought. I changed the hard drives and video card back thinking I might be on to something. Back to same issue.
Any thoughts?
