Question: On a computer here when first powered on the USB wired mouse is not recognised. The light under the mouse is not lit up. Other usb hub's and keyboards work fine. Disconnecting it and reconnecting it fixes the issue, even after a restart - after the pc is switched off for a length of time (for example overnight) the problem reappears.

I swapped the mouse, updated the bios and installed updated intellimouse drivers, turned of power saving on the usb ports. Any ideas?

Answer: 
I recall reading somewhere that software raid set up in Windows is not easily readable/mountable from Ubuntu and vice-versa (correct me if I'm wrong), you may wish to research that first just in case.

I have a similar set up to what you're after though (I have Win7 on SSD, 2x 500gb in RAID0 for storage, and 1x 500gb hdd for important data with a partition for ubuntu) My steps were:

1. Setup the RAID via the BIOS (I used on-board Intel RAID controller as it seemed the easiest option).
2. Install Windows 7 onto SSD.
3. Partition the 500gb drive from Disk Management in Windows.
4. Reboot with ubuntu disc and install onto the partition.
5. Ubuntu installer should auto detect the Win7 install and setup the boot loader for you automatically.

Only problem with my setup is that since onboard RAID controller is "fake" RAID, I need to do a few more steps in Ubuntu to get the RAID0 volume to show up properly. It shows up fine in Win7 though.

Hope that helps in some way :)
if you plan to do the system install on win7 and ubuntu, you should install win7 first and ubuntu later, as suggested by MarkM above.

then, for the matter, depending on whether you plan on using software or hardware raid, you should format the volume *after* ubuntu & windows 7 installed (to minimize the fuss associated with multiple disk sets while installing ubuntu) and adjust the set accordingly in windows (e.g. install the RAID card/raid set driver, etc.), and in linux. 

you need to note too, that the current kernel driver for ntfs is limited in terms of write support although it reads almost perfectly. check out ntfsmount ( <http://www.linux-ntfs.org/> ) if necessary.
