Command prompt error.

Im having some command promt issues. When i type in the netstat (same with ping) i get a message with this error: Command Prompt - netstat The NTVDM CPU has encountered an illegal instruction CS:0000 IP:0077 OP:f0 37 05 0c 02 Choose 'close' to terminate the application.

Then i get the choice to click ignore or close. So I click ingnore, and I get a bunch of crazy characters and it wont let me type anything.

Could someone help?
