Having problems with your Sony VGN-SZ640 Notebook ?

Vaio SZ640 restarting on it's own.

\015 My SZ640 restarts on its own when run in 'speed' mode. Before this happened I noticed that my video driver was acting up. Once it restarts the display is messed up with horizontal lines during the booting process. Any \302\240ideas?\015

Answers :

I have this same problem as above with the same model. I had a fan and over-heating issue. Now, only zig-zag lines across my screen at start up. Please advise.
You may need to re-install the driver of the video card or at least update it. else this immediate restart may mean that the Laptop is overheating. check that the fan is working.
