I have a dell xps desktop. Its pretty old (2007 model I think) and I can't get it to run anything except my vista that I have that came with it. Also it pops up with "floppy disk 40 error" before booting up every time. Got any ideas? I'd like to run windows 7 or 8 on it but planning to do some serious updates soon like GPU, CPU, and motherboard. Should I just wait? Or will it work to get the OS and then upgrade?
