[Dioxid3]

Okay so my problem, as you can see is that my laptop suddenly shuts down while playing games like Sanctum,Just cause 2 and Mass Effect.

I got this laptop last september 2010, Acer 5741G :
Intel Core i3-350M
2.26GHz, 3MB L3 cache
4 GB DDR3 RAM
Nvidia GT320M
1 GB ram
2,6 GB of divided ram
Realtek Audio

I did look at other topics with same issue,but with no luck.So i beg you guys here at tech support,Please,Help me )=
It's a shame that new laptop crashes like this.

When i look up in event viewer, i get this :

Hello and welcome to TSF
this seems to be a heating issue
download SIW from my sig, open it and choose "Sensors" under "Hardware"
check the temps.
play a game for about 10 to 15 mins or before the laptop shuts down, minimize it and recheck the temperatures again.
please post both temp states (idle, under stress)

Hi again.

Yeah I played both Just cause 2 and sanctum,but i was surprised about sanctum since it crashed always in same spot,except for this time.I tried it with 3 different resolutions , and once with fullscreen,it did not crash.I noticed also that at the specific "crash spot" the temperature hops 5 degrees (celsius) up. I did manage to take screenshot this time.

Now, I wanted to test out Just Cause 2, since it was first game i experienced this crash before.It crashed twice.Both times my PC just shuts down and i gotta manually start it. The temps were something close to these (before crash):

Current Min Max
CPU Core
#1 87 52 88
#2 85 48 87

GPU
80 50 82

Now I was surprised how much this game stresses the GPU,since it felt like CPU heavy game.I have started really to hate this game,since it should run on max on my system (according to recommended requirements and windows performance index) it gets fps drops at higher resolutions than 800x600.(I played in 800x600 when it crashed).

I mean like,BFBC2 ran on medium better than just cause 2 on medium,and bf allows you to punch boards and drive a tank through wall.I played whole campaign without a single crash nor CTD's.

Then I got Mass Effect 2.Goes on full aswell,it crashed,i digged all around,no answer.Lifted my laptop on map case to 60 degree angle,no crash.

And if this is about heating issue,oh god i will loose my laptop for months,since the store where i bought it from is known for lazy support and fix crew.

Edit Oh god those temperature diagrams look alot better in edit box than in real post
