Here's what happened and the problem this morning:

1) Computer is on a self start for 7am every morning.
2) Computer boots but is continually looping (turning on, monitors remain on stand-by, then shuts reboots - it's as far as it gets - no post, bios - nothing).
3) I shut it all down (Hard shut down on power button) open up case, remove battery from the MoBo, waited 5 seconds, and then put it back in. I had removed power cable of course.
4) Computer now boots up POST screen and I can enter bios - Temps are all normal - everything is sound and back to default Bios settings. I had it previously over-clocked, so originally thought CPU had finally died.
5) Now, when I check in Bios, the Hard-Drives are showing as two separate ones. They were originally in RAID (1 I think?) - So I knew immediately that it wouldn't boot windows...
6^) Turns out, it won't boot into windows... "Missing Operating System"...

I've had this problem before and resolved it with a very simple method... Unfortunately I have no idea what I did last time...

I have no external devices plugged into my PC (USB sticks etc).

If I boot the Windows 7 CD and check out any repair options, there is nothing to repair because the HDD's are not in raid = no operating system.... (Which of course is not true)

It's definitely something to do with how to get my HDD's back in to Raid option as opposed to two separate HDDs'...

Any help would be massively appreciated - I have ridiculously important documents / work on there and am a little stressed to say the least right now :(

Update:

1) Decided to move SATA cable slots (2 cables) into two different slots - computer was off - power cable still in with power switch on.

- Now has reverted back to just ON, no rebooting and absolutely NOTHING coming on the screen. No beeping noises too.

I powered it off, removed PSU cable, removed battery (and pressed the red tiny button on motherboard), put battery back in, PSU cable back on, and it still is just doing nothing. This process allowed me to boot up to Bios, but now it just boots up and does nothing?!?!?!?

OMG! RIGHT - I have it back to the point where it is now saying "Missing Operating System" - all led lights on Mobo are green. So there should not be any hardware issues - or if there were, not any more.

Post screen passes, and I do not get any beep noises. It just does all the checks and then sits at "Missing Operating System" which is simply because the two hard drives are not in RIAD and they need to be?

Anyone know how I can set it up into RAID!?
