Graphics card may be faulty

Hi All,

I have a strange problem.  I'm trying to play a game on a HP laptop but it begins to act unusually and sometimes crashes completley.   When in the game the graphics become jumpy and I get triangles and lines as if the game is not able to render the graphics correctly.  There are no such symptoms in Windows or any other applications.  I have tried re-installing and updating the graphics drivers, discharging static by removing the battery and holding the power button.  There has been no improvement.  I have even re-installed the game itself and looked on forums for anyone suffering similar problems.

I have called HP and they say that if it was the graphics card I would be having problems in windows and other applications aswell.  I'm not sure about this as the problems seem to only happen when the card is trying to draw 3D objects.  They now want me to re-image my system.

Can anyone advise if it does sound like a card issue, or if you have any other steps I can try.

Here are the laptop specs:

HP Pavillion DV6 Notebook
Core i3 - 530:  2.97GHz
Windows 7 Home Premium
ATi Radeon Mobility HD5470 Premium Graphics

Thanks in advance!

What comes to my mind is to benchmark the video card, which will make your pc act like if you were running a video game. With this we can see if your pc freeze or cause any problems when rendering.

Download and install basic version. Run the test. See if it run the test successfully. Also paste results.

For more information please post the game you are trying to use.

What are you trying to play and has it played OK in that resolution previously?  Although Mobility cards have improved for 3D and DirectX they are still not as good as their desktop equivalents.  If this has never played properly check the recommended graphics specs for your game.
you can test it by installing another OS in a partition, or on another disk

this will show clearly if the problem comes from software or not

OK, I seem to have solved it.  After running 3D Mark, I discovered that the card being used was the Intel graphics adapter, even though the graphics were set to high performance and auto switching turned was off.  There was no option to specify which card I wanted to run in the crappy InsydeH20 BIOS, so I just went into device manager and disabled the Intel card, it has been working fine now for the past few hours.
