I purchased an HP computer about a year ago which came with Windows 7 Home premium 64 bit. I upgraded my motherboard and my computer would not recognized the OS. The OS came built in the computer so I have no recovery discs, so I called to see if I could get a hard copy and I was denied unless I purchased the software again. Since I already purchased the software when I bought the computer I should be able to download it or something and put it on a disc. Is there anyway to get a copy of my OS without having to spend the 99 dollars to purchase another copy? I don't want to have to pay a computer company again to reinstall it for me.
