Before I explain my situation, I want to make clear that I do not know much about hardware at all. I had a lot of HELP from my boyfriend who was the one that picked out new parts and also installed the parts I bought. However I'm not completely computer illiterate and with clear instructions I can figure out what to do, but please be patient with me if I don't include all of the needed information in this post. I'll provide what I know.
A few months ago I decided that I wanted to upgrade my PC. So firstly, I started with my processor. I was using AMD Phenom II and upgraded to AMD FX 8370E, but turns out it wasn't completely compatible with my power supply, and there were some issues with my motherboard too so I ENDED up upgrading those two as well. I have the Sabertooth 990FX R2.0 mobo and SeaSonic SS-750KM3 power supply now. My boyfriend installed all of the new parts, and my PC does start up fine, but windows fails to start no matter what I try. I am using Windows 7 x64. It doesn't boot from the CD either. There is a quick flash of a bluescreen before it asks to either run startup repair or start windows normally, however it doesn't show an error code during the bluescreen. At first we thought my motherboard was defective so I sent it back and got a replacement, but there is no difference and I'm still having this problem. We have tested my RAM as well and that doesn't seem to be problem, but we are running out of IDEAS of what it possibly could be. Any suggestions or solutions will be greatly appreciated. I've been without my PC for months now and I miss it so much! When a user installs a new motherboard, Windows must be installed again.

This is by design. Even if the two motherboards are similar, Windows must be specifically installed for either motherboard. Each motherboard has its own set of drivers provided by the maker.
When you got the new motherboard, there should have been a CD with he new driver software for that motherboard.

Set or enable the BIOS to start from the DVD/CD DRIVE and do the full Windows installation. There might be an option to repair the installation. That might do much of the work, but later you still have to install the drivers.
