The NTVDM CPU has encountered an illegal instruction.
CS:1217 IP:0179 OP: 63 72 69 70 74 Choose 'Close" to terminate the application.
This message keeps popping up every 5 seconds. I click close and it pops up again. I cannot choose the "Ignore" button as it just keeps reappearing. Cannot close the window either. Have tried Task Manager to remove the process. Task Manager does not see it.
I have Windows Vista on a Dell Laptop. How do I stop this? What is the problem? Will purchasing a registry cleaner fix this problem? Which registry cleaner should I purchase?
