There it goes again—your computer is frozen like a log in January—how frustrating! Computers can freeze for a variety of reasons. The program you are using may not be responding or may be lagging (waiting for another process to finish before it can respond).
There may be a hardware problem with your machine. There may be a virus or spyware issue attacking the programs you are running. There may be a problem with your drivers (the programs that run your computer’s basic hardware like the monitor, disk drives, etc.).
