Hello all, This is my first thread posting. I am having a similar problem that was reported earlier on your message board concerning an error message that consistently keeps popping up, named "16 bit MS-DOS Subsystem". The message is below: C:\WINDOWS\TEMP\h91746.exe The NTVDM CPU has ecountered an illegal instruction. CS:0dc0 IP:01d4 OP:63 68 65 2f 31 Choose 'Close' to terminate the application I have tried to do everything that was instructed by howard_hopkinso's posting (http://www.techspot.com/vb/topic44921.html) and now, I'm at the last task where I need to post my hijackthis.txt file as an attachment, for which I've included the file with this thread. Any help is greatly appreciated!!!
