  1. I just left my PC Online, (As I always do...) When I came back from school this darned error is everywhere saying
    16 bit MS-DOS Subsystem
    C:\WINDOWS\system32\psexec.exe
    The NTVDM CPU has encountered an illegal instruction
    CS:0db9 IP:0114 OP:65 3e 63 78 7a Choose 'Close' to terminate the application

    and it wont stop.....I get about 200 of these things in 5 mins.. so its spamming like hell..
    I did a reboot on my pc but it just had different files and still ended with spamming of the psexec.exe error. FIrst i got these
    16 bit MS-DOS Subsystem
    C:\WINDOWS\system32\Down.exe
    The NTVDM CPU has encountered an illegal instruction

    then
    16 bit MS-DOS Subsystem
    C:\WINDOWS\system32\Nogui.exe
    The NTVDM CPU has encountered an illegal instruction
    then
    16 bit MS-DOS Subsystem
    C:\WINDOWS\system32\BindF.exe
    The NTVDM CPU has encountered an illegal instruction
    and Finally Spams
    16 bit MS-DOS Subsystem
    C:\WINDOWS\system32\psexec.exe
    The NTVDM CPU has encountered an illegal instruction
    So my Process Memory is getting taken up by just these errors.

    Can anyone help me get rid of this error w/o the reformatting solution..
