I had the WMPDXM.DLL message when i tried to open explorer. I attempted to fix this and to start my computer in safe mode. When I do this is says "Keyboard Failure". It will start in safe mode but the keyboard will not work. When I tried to restart it normally it brings up the box that says "windows was improperly shut down ... checking for errors" then it brings up the box that asks for the password after I click cancel it says "cmdninst has caused an error in <unknown>. cmdninst will now shut down." And that's it. It will not bring up anything else; no icons, no taskbar, nothing!
I know it had some errors on it because it was also having the RUNDELL error message and I am sure there was a virus (or several).
What should I do at this point to begin fixing the problem? Thanks for all your help!
