Buzzing Computer

I have a pc I use to record programmes I want to keep off my sky box and edit. it consists of a gigabyte GA-X38_DQ6 mobo and ATI graphics. I have two raid 0 disc arays attached to it one with the operating system plus 2 storage partitions and the other to store the output from my capture card before being edited and it has been working perfectly. I have run out of space on the secomd aray so I am trying to reorganise my system to one raid 0 aray with the operating system on and a large single disc in a hot swappable box so I can swap in and out the drives holding my edited files which up to now have been in a separate box. As I wanted to try not to have to reinstall the operating system etc, I have repositioned the discs in the drive bays which make up this raid array and connected them to the same mobo ports they were on so that the raid software would find them and boot normally. However when I switch on and enter the bios there is a continuous buz from the PC and the bios cannot detect any hard drives. Online it is said that a continuous buz means a problem with the graphics card so I have removed it and reseated it to no effect. I have tried another working hard drive with exactly the same effect. It buzzes even with no hard drives attached. I do not have another grahics card I can try but I can't see why this should be a problem as the PC was working fine upto this time when I tried to reorganise the drives. All I have done is unplug the drives at the drive end and haven't altered anything else. Any suggestions please?

Has the PC got built-in graphics that you can switch to so you can boot the PC without a GPU in to make sure that the card is the problem?

look for VGA/HDMI/DVI ports on the back of the mobo

No, only onboard sound which I don't use as I have a creative soundcard attached.

I have solved this problem. Though it was only altering the location of various drives in the case, I had retained the original connections to the mobo so it saw the same hard disc on the same connector. For some reason the bios objected to it and read that the cpu fan was not spinning and so issued this buz. loading an optimized bios sorted this out tough now I will have to reinstall windows. Why it objected to the cpu fan not spinning I know not as it never spins at boot only when things have warmed up a bit.
