How come my computer will just all of a sudden freeze while I am using the Internet?

Q: I have a Toshiba Laptop, L45 Windows Vista. My virus scans are current and show no problems. However, when using the internet, most of the time after I am on for a while, I will hear a chirp, then everything locks up. You can see the pointer, but it is frozen. Cntr, Alt, Delete will not even work. You have to do a hard shut down, then power up again. Sometimes you get the option to open normally or in the safe mode.

Do you have any ideas?
