2007 HP Pavilion m7747c running Windows Vista Ultimate

I got this PC at a Valley Thrift Store, but this time, in Evendale, Ohio for only $25. It came with a thermaltake PSU, but I replaced it. It didn't come with RAM or a HDD so I used two 1GB RAM Sticks for a total of 2GB of RAM. I also used a 160GB HDD despite the spec sticker saying 320GB HDD because I only had some 160GB HDDs alongside with a 80GB HDD. I also put an HP OEM Copy of Windows Vista Ultimate because I couldn't find a HP OEM Version of Windows Vista Home Premium, which is what would come with this computer.
