I am currently observing usual shut down after freezing my system on Linux Mint 10. I recently installed Linux Mint 10. I was really impressed with the speed of the system as well as with the graphics which looks awesome on my computer. I just like the system with the performance. But I just have one concern with the Linux Mint menu. Whenever I try to type something which is not installed in the Linux mint menu my pc "freezes" for 5 to 10 seconds and suddenly shut down. So I need to restart the entire system again and also need to do start the work from the scratch so anyone know how to solve this issue or anyone have faced this type of situation early so please let me know guys. I cannot make out why it is causing so much issue with the Linux mint menu. Help will be grateful.
