HP Pavilion dv7 1130en - Shuts Down [ Edited ]

[Mastrel]

Hi All,

I know that this question was asked too many times throughout the Internet, and this forum, but still, I didn't find the solution to my problem.

My laptop is about 3 years old. For the first two years and a half i didn't have any problems at all. But a few months ago it started to shut down from time to time, with no apparent reasons.

My first though was - overheating. So I disassembled it and cleaned the heatsink, cooler and vents. I have also reinstalled Windows and updated all the drivers including BIOS. It seemed, that problem was solved. It worked fine for a month or so, but I didn't really used it intensely. About a month ago is started to shot down again.

I thought that it might be the time to change the thermal grease on chipsets, so I've done it yesterday. For the first three hours it worked fine, then it shut down while I was playing a 3D computer game.

I actually noticed, that it tends to shut down more frequently when I run heavy 3D applications, not only games, but also stuff like benchmarks or Maya 3D, etc. But it also, sometimes, shuts down when I'm just working in Word, or Visual Studio.

Hard Drive and RAM checks didn't found any errors, same as Intel Processor Diagnostic Tool.

I am using it on AC power withought the battery because it's dead.

So I'm asking you guys, do you have any ideas what that might be?

P.S.

Temperature reading before shutting down while playing a game are:

Core #0  ~ 70°C

Core #1    ~ 74°C

Graphics  ~ 76°C

MotherBoard  ~ 70°C

I know that 70° for a motherboard is a bit too much, but it also shuts down when all the readings below 40°C,

so that shoudn't be the problem.

I had this computer for a year and without any problems, but after a year, the same thing began to happen. Computer shuts down when I try to play 3D games. 

Likewise, I've been through every step above mentioned to try to  fix the problem and even sent it to a professional repair shop, for cleaning and diagnostics. They say the computer is just fine but the problem persists. 

For the past days it has gotten much worse: computer now shuts down when I am streaming video from Netflix as well. 

I've been through every forum on the internet and I saw NO solution, anywhere. Everything that is suggested I tried.  It is very frustrating to see that in the manufacturer's forum, the questions about the problem remain unanswered with no word from HP support personell.
