Laptop shut down in game

[navidnouri]

i am likely a gamer and most of the times i play games with my laptop, i usually play about 8 hours of game with my laptop in one day totally (in about 3 hour period of play and resting for 30 min and then play again with no power off)

sometimes after hours of playing the laptop turns off in this way:
graphics halt for about 1 sec the sound may be go noisy or repeating itself and then it monitor turns off and after laptop goes off i can power on the laptop immediately after and work or play with it without issues again

this power off problem does not repeat in a pattern!

i guessed for overheating so i loged the tempreture using Nvidia performance tools both CPU and GPU

and the last results where this:
Time,GPU/GPU Temp,CPU/CPU1 Tj Temp,CPU/CPU3 Tj Temp
Sun Sep 08 21:05:53 2013, 68 °C, 69 °C, 69 °C
Sun Sep 08 21:05:54 2013, 68 °C, 69 °C, 69 °C

Sun Sep 08 21:05:57 2013, 67 °C, 69 °C, 69 °C
Sun Sep 08 21:05:58 2013, 67 °C, 69 °C, 69 °C
Sun Sep 08 21:05:59 2013, 67 °C, 69 °C, 69 °C
Sun Sep 08 21:06:00 2013, 67 °C, 69 °C, 69 °C
Sun Sep 08 21:06:01 2013, 67 °C, 69 °C, 69 °C

my guesses are:
RAM malfunction or Audio driver problem

laptop model: VAIO VPC-f134FXB
GPU: nvidia 425m driver: almost every driver and now it is 326.80
CPU: i7 Q740

did memtest86 and rams passed all tests without errors

Do you have the lastest bios, chipset, sound and graphic drivers installed? cause that might be already solved in some of the updates. Try and say something

I had a similar issue, but mine was just shutting off randomly~ sometimes in a game, sometimes just while looking at the internet. Anyway, after multiple searches and no luck, I just randomly bumped the power cable, and it shut off. I checked all the connections, and they were fine, so I decided to try a different cable that I had in the house. It hasn't shut off since. In my case, it was just a bad cable. good luck.

well i mamanged to install the latest BIOS available for my laptop, and tried the sound driver installation too from both Sony support and the vendor (Realtek), and almost tried every graphic driver (beta and whql) from Nvidia website, but couldn't manage to install chipset driver somehow it skips the installation, from what i found when it detects the driver is installed don't install the driver!!, it is intel chipset inf tool

well it's a laptop witch always have a battery! don't think the cable can cause any problem!

hum, you did install that before my question? just to be sure if you had already did that or just did after my question.?

Btw i dont recommend you to install nvidia beta drivers, just install stable ones. Have you used the chipset drivers from sony support?

now being more extreme, when was the last time you formatted your pc? in a despair mesure i would recommend do a clean installation and and install the drivers. Cause that might be some messed up .dll or something

Get the latest nvidia whql drivers.perform a clean installation(it will wipe off your old drivers).also are u overclocked?when was the last time you get your thermal grease repaste?

]also one thing i have remembered now, if you are playing 8 hours in a row...what is shutting down the pc is not the cpu. get gpuz or another and log the gpu temeperature

use another gpu monitor, dotnt think the one you used is giving the correct information

well i always try to keep my drivers updated and i usually update to most new drivers. and i forced to install chipset driver as well with a command line, sony driver is the same as intel one so i install the newest intel driver.

i have done clean installations and problem shows up after some time. (maybe an application incompatibility or sth happens when i install it)

no i am not overclocked and i want to lower the clock to see if the problem can be removed!
and as my PC is a laptop i myself never could make it to the removing heat sink part to re-paste the grease. but whatever the situation is the temperature is read from the processor itself not the heat sink i guess?!

i give it a shot see if it differs!
