I meant to write MS DOS, not DIS. I was downloading songs one night and suddenly my computer crashed. Whenever i reboot it, the same message shows up after i log onto admin. : 'C:\windows\system32\winlogon32.exe The ntvdm cpu has encountered an illegal instruction.' Whenever i try task manager, it says the admin. disabled it, so that doesn't work. The only things i am able to see are the message and my desktop backgroup. no icons or toolbar. so i can't onto control panel or anything. Does anyone know what this is? and How can i fix it? I can't run an antivirus program because i cant access the computer other than logging in.
