Vaio SB - Screen Freeze/Hang

the screen is hang and no response from mouse and keyboard. it happened 2-3 times per month and both driver (intel graphic and amd radeon 6470)

for radeon 6470, got driver is problem which the screen will hang for around 10 seconds and suddenly the screen is flick and no more problem. the system notified that the driver crashed and it recover back.

does anyone know what is the problem? thank you.

 

have you updated the AMD driver?

Do you frequently go to standby?

 

i'm not sure the amd driver is latest or not but i use vaio update to check the latest driver...

i always hibernate my notebook and monitor off instead of standby....

 

well, luckily for you, Sony's general hate of update drivers (okay, not really a hate, but they are very slow on updating graphics drivers, when a new one comes out almost every month [mainly due to games, but lots of minor bug fixes, too]), has been palliated with...

the AMD drivers are the official onces from AMD, the Intel ones have a modified INF (setup) file, in order to support the switchable graphics.



I will note, most of the time when my GPU driver crashes (in the past, I haven't seen it happen in a long time), it due to a bad program (this is normally resolved with newer drivers) or because I simply didn't do a full reboot for too long.

Good luck!

 

My computer freezes on me at least once a day. The screen hangs up, and I cannot move anything at all. I have Coretemp running to see if it's the temperature, and it can't be the reason. I have the computer elevated now, with a fan (a deskfan) blowing air into it from behind while the laptop is propped up.

I can't figure out why it's freezing, It will freeze on me at all times. (1 power point presentation running, or just browsing the internet).

 

Have you tested your HDD?
