I disassembled my computer a few weeks ago and just reassembled it yesterday. Although it was working fine when I took it apart, I'm running into a problem now. When I boot up the computer, it gives me options to enter the BIOS and I see the normal Gigabyte screen with a loading circle, but after that stage, I'm taken to a dark blue screen where I can't do anything.

I'd read earlier that this problem often occurs because of an issue with graphics cards so I replaced my old gtx770 with another gtx770 to see if that was the problem. Initially, that solved things. I was able to make it to the Windows login screen and to log in. Today, however, I'm having the same old problem--booting to the dark blue screen and not making it to any part of the OS.

Any ideas on where my problems might be coming from? Thanks
