Hi, I've just installed two WD Blue 1TB HDDs and want to set them up in RAID 0, but whenever I press DEL during start up I get nought but a black screen. The same happens when pressing F12.

As far as I'm aware it worked fine before I put these in (I don't actually remember needing to enter bios, though I probably did because I also have an SSD and a 500GB HDD in there, so probably had to configure boot drive).

Any ideas?

Some spec

GA-970A-UD3
16GB RAM
Gigabyte 7970
FX-8530
Windows 8 64-bit

Bios version FC

a little additional info.

It isn't displaying NOTHING, or my tv would say 'no signal', it's just black. Main monitor is on HDMI at 1920x1080 and secondary monitor on DVI to HDMI at 1280x720. Could the resolutions have anything to do with it? I've done some googling and seen it pop up, but I'm pretty baffled here.

I've added both the HDDs via disc management and they're showing up fine.

More info, I opened a ticket with Gigabyte, who informed me I should reset the CMOS. Just did that and now my pc doesn't boot. I just get the same black screen as I did when I tried to enter BIOS.

Not happy now, it booted fine before I did that.
