Bluescreen on fullscreen mode

[Brutes]

When I play video games in fullscreen mode, the game will start to flash a bit, and than my computer will freeze and pop a bluescreen. I all started bout a week ago, Im not sure what caused it. Ive tried to run system restore to reset te pc to a date where everything was still running fine, but that did not help. Ive also updated, reinstalled the latest drivers, still didnt help...

Operating system: xps630i
Processor: intel core2 quad q9400 @2.66GHz 4(CPU) 2.7ghz
Memory: 3068mb ram

Could be the sign of a defective card,can you test it in another system ?

 

[Brutes]

Not really, its the only pc worth using in my house. Anything else I can do to know the problem?

Try an older driver, but this time do a clean install of it not just a reinstall.Here is how

1_Download and install "Driver sweeper" from Guru3d.com and install
2_Go to add/remove programs and uninstall the driver and reboot
3_Boot to safe mode and open driver sweeper,then click on ATI and choose clean
4_Reboot and boot normally to windows and install the new drivers after that you need to restart,and its done

Is the card still under warranty ? if it is,then RMA it.

Is the card still under warranty ? if it is,then RMA it.

So I assume my graphics card is broken?

Unfortunately,it's probably your GPU causing the BSOD on full screen.

I get an atikmdag.sys error in my bluescreen, and I see alot of other people havign similiar issues with ATi cards

 

[Maziar]

Yes that's a common error.Not between ATI cards,but in Nvidia cards too(nvlddmkm has stopped responding....)
