I don't know a whole lot about computers and need some help. I have both 2005 and 2006 sp0.0 installed on my computer. It is becoming unstable. I try to open a file and the whole thing will shut down. Also, when I click "File", "Open", the first 24 file names have tilde's in front as if they are files that are already open. That seems odd. Is there a procedure somewhere on how to completely remove Solidworks and reinstall. Do I need a doctorate in computer science to accomplish it? Do I even need to do this? My computer is running Windows XP pro 2002 service pack 2. I know my computer is up to the task speedwise and memory...
