Hello everyone, I previously posted a thread asking for help with a serious problem I am having. I recently purchased a new motherboard and cpu (sabertooth 990fx r2.0 and amd fx 8350) I installed it and updated the bios for compatability. However, when I tried to boot into windows, I got a blackscreen indicating that windows failed to start with maybe hardware or software being the cause. Now my question is knowing that I have to do a clean install, I have this problem. I only have a window 7 home premium 64 bit upgrade disc and not the full version. Is it possible to still do a window 7 installation or do I have to buy a full version window 7 disc. Thank god I back up all my files and can just restore them once the installation is complete. If anyone can give me any advice it would greatly appreciated.
