Acer Aspire 8930g unsolvable problem?

Hi,

i've been having trouble for quite a long time with my acer notebook 8930g
- intel core 2 duo processor T9550 (2.66 GHZ, 1066 MHz FSB 6MB L2 cache)
- 18,4" Full HD 1080p acer CineCrystal LCD
- Nvidia GeForce 9700M GT Turbocache
- 4Gb DDR3
- 1000GB Dual HDD(500GBx2)
those are the specs,
iv'e read on a LOT of forums problems like mine though iv'e never found a solution for my problem, i think its a special one!

so what is the problem?:
If i'm playing a game, (Battlefield2, The sims 3, ...) the Laptop Shuts down all of a sudden after a little while.

i'll tell you what iv'e tried, and what i'm sure of

i tried:
- Cleaning out all the dust
- changing my Nvidia settings
(conformant texture clamp -> Use OpenGL spec.
Trilinear texture optimization -> Enabled
Force mipmapping -> Trilinear
Vsync -> Forced enabled
is what they recommended to change, though i can't find the mindmapping or texture clamp so i haven't been able to test that one out a 100%)
- checking my laptop on spyware
- turning my laptop upside down and shaking it a little bit (yes that was a - --- solution that worked for someone)
- playing the games on low resolution
- putting a ventilation cooler under my laptop
- reinstalling the games

i'm Sure its not a heating problem cause my laptop never exceeds its maximum heat level which iv'e checked with a program i can't recall the name of.

i'm playing the games (more like Trying to play..) with the laptop plugged in to the power cable and my battery is doing fine by the way.

the laptop is less than a year old and i bought it new


So? any ideas to what it might be ?

i'd REALY appreciate the help! and even more a solution!

thanks in advance

Have you tried a crash dump analyser? It's a good starting point to see if a driver is causing the system to go down. (Google: WhoCrashed)

 

Try running the laptop without the battery see if this changes anything.

 

i have the same problem with 8920g 9500m gs

 

hi, thanks for your reply i tried the crash dump analyser you adviced me and here is the analyses in the attachment

 

i've tried this but it didn't help :s

 

did you tweaked the laptop l2 cache?
try removing you anti virus
last try if it have 2 ram card try 1 ram first

 

According to the dump, ntkrpamp.exe is identified as the source of your crash. Are you running any third party power management software? The simple way might be to simply reinstall your OS.

You should be OK from there. This doesn't seem to be defective hardware but simply a driver issue.

 

i'm not running any third party power management software, i doubt it will help cause i've had the same problem when my laptop was running Windows vista ultimate, after formatting my laptop to install windows 7 I was still having the problem.
