My laptop is a refurbished ASUS G46VW. It was supposed to have installed a dedicated Nvidia GTX 660M graphics card, in addition to the integrated Intel HD 4000. While the laptop recognizes that such a video card is installed, if I try to set the Nvidia as the default graphics card, games that I try to play will consistently run into issues. I have tried reinstalling and updating the drivers for the card. When I set the integrated card as the default, and did not run into any crashing issues. I have a feeling that the Nvidia Geforce is either malfunctioning or was installed improperly.
The more severe issues occurred in games such as Dishonored and Bioshock. Occasionally I would get visual artifacts. In the most severe cases, my computer would blue screen with "DPC_WATCHDOG" error and crash.
The laptop is about 2 years old, refurbished. I have not attempted any overclocking. In the past, I have attempted a couple system repairs upon boot-up. They only helped mariginally, and not for long. Additionally, I had consulted a technician briefly who instructed me to perform a memory test on the laptop, which came up clean.
I am running on 64-bit Windows 8.
I would like to know if there might be any solutions to my issue without cracking into my laptop, because I am uncomfortable with laptop anatomy. However, if necessary, and with proper instruction, I would be willing to do so.
I hope this is enough information to be diagnosed. Please let me know if there is any more information that would be helpful, so I may provide it.
Thank you
