I've bought a pcv-rs602 sony vaio just one week ago and i've already experienced some problems. For istance, it's the fourth time that my computer locks up after a while, when i watch tv by giga pocket and simultaneously i use other applications, such as internet explorer or acrobat reader. Afterwards, I can't move my mouse and the ctrl+alt+detete function doesn't work. I can only listen to the audio of the tv program, but the image on my monitor is frozen. I can only turn off the computer pressing the power button. The same happened whatching a dvd. Please, can someone help me?
