I have a windows 7 computer. I found an old computer up in my attic that I decided to set up as a server. It had no CD Drive to install windows, so I "borrowed" one from my main desktop windows 7 computer. I've installed everything just fine, and I have now replaced everything back in there appropriate computers. The problem is, my main desktop Windows 7 goes to a black screen with no mouse after I login. I type in the password, press login, it takes a little bit longer than normal to login, then goes straight to an evil black screen and freezes. It worked fine RIGHT before. There were no software changes or hardware (besides the temporary switch in CD drives). I've tried starting it with no drive as well to no avail. Thanks if you can help!

Hi, Whether you get a BSOD? If so, I suggest to try boot from Safe Mode to see whether the issue still occur. Also, you may try to use System Restore to restore to an earlier point. If the issue still happen, I suggest to contact our CSS team for better help because of this need to debug the kernel dump files. It already beyond what we can do in this forum.
