I'm using Windows XP SP3 logged in as the administrator.

I had RAID Mirroring running. The motherboard broke earlier in the year. When I got a new battery I did not resync. I just use the disks as two separate disks.

I searched Google for the errors but I didn't find anything detailed enough.

The following Microsoft components are in Add/Remove programs:

• .NET Framework 1.1
• .NET Framework 2.0 Service Pack 2
• .NET Framework 3.0 Service Pack 2
• .NET Framework 3.5 SP1
• Microsoft Compression Client Pack 1.0 for Windows XP
• Microsoft Office Enterprise 2007
• Microsoft Silverlight
• Microsoft USB Flash Driver Manager
• Micrsoft User-mode Driver Framework Feature Pack 1.0
• Microsoft Visual C++ 2005 ATL Update KB 973923 x86 8.050727.4053
• Microsoft Visual C++ 2005 Redistributable

This is the installation log:
