I have a computer that is used by another person where I work. He brought the computer to me stating that he could not get anything to come up after he turned it on. After talking with him, he told me that a few days before this started happening he had gotten a pop up saying that his computer was infected and asked if he wanted to run this program to check for viruses. Of course, he ran the program AND cannot remember what it was called.
So, after messing around with the computer these are things I've been able to come up with.
After starting the computer up, it takes roughly 30-45 minutes for the login screen to appear. After you login, it takes another 30-45 minutes for the background to appear, and then I start getting a Data Execution Prevention error with "Run a DLL as an Application" as the name, and Dr. Watson Postmortem Debugger errors. I was able to bring up the task manager and determined that there were roughly 100 instances of Dr. Watson running. When I closed one out, another one would come up.
I tried booting into safe mode. Again, it takes a long time for the login screen to come up, and then after that all I get is a black screen. No error messages though. Also tried booting into safe mode with command prompt. The command prompt comes up after login, but disappears after a few seconds.
I've never had to deal with this problem before so, my question is: Is there anything I can do to find out what's going on with this machine without having to reformat it? Any thoughts or suggestions are greatly appreciated!
